My Comments

The Sony WG-C10N is like most other mobile network-attached storage devices in that it requires the mobile device to be effectively attached to its own wireless segment. Of course it can work as a bridge between an existing Internet-connected network and your device like most mobile NAS devices. As well, it requires the use of a mobile platform app or the use of a Web front for users to benefit from the data stored on the NAS using the Wi-Fi network.

This means that it can’t work with existing wireless home networks, nor can it support SMB/CIFS network file transfer that is common on regular computers nor can it serve audio-video content to DLNA-capable media devices.

But unlike the other mobile NAS devices that are on the market, this device works simply as a file server for attached SD cards or USB flash drives rather than using an integrated storage medium. This is more so for those of us who want to use higher-capacity memory cards or USB thumbdrives or have a collection of different SD cards / USB thumbdrives for different applications.

It also works as an SD card reader for those of you who don’t have an SD card slot in your computer or similar device (think of the Dell XPS 13 Ultrabook that I previously reviewed) to view or download your digital camera’s “film roll”. As well, it is one of the first “mobile NAS” devices that can serve as an external battery pack for your power-thirsty smartphone or tablet.

My Comments

SanDisk have jumped on board the bus as far as mobile network-attached storage devices are concerned.

Here. they have released two devices but both of these devices are similar in functionality to the typical “mobile NAS” is concerned. They require that you connect your laptop, smartphone or tablet to their own wireless network but the SanDisk devices have a similar Internet-access “bridge” mode to what the previously reviewed Kingston mobile NAS has so you can benefit from another Wi-Fi network for Internet access. They also require you to install a manufacturer-designed app on your mobile device so you can get at or put files on these mobile NAS devices from your device’s control surface. There is also a Web front for gaining access to the files hosted on these devices from a regular computer.

Of course they have their limitations such as not supporting SMB/CIFS data transfer used by every regular-computer operating system or not supporting DLNA media-server functionality so you can “pull up” media stored on these devices on a smart TV or similar device. They don’t even allow you to link them to a regular small network so they can become a NAS for that network, which could come in handy if you use a “Mi-Fi” device on the road or simply annex it to your home network just to transfer data to and from the device.

There is a USB connection that is used for charging these devices from any USB AC charger, car charger or external battery pack as outlined in the “Gadget List – Essential Smartphone And Tablet Accessories” article. But this also is used for transferring data between a regular computer and these wireless NAS devices as if they are a USB memory key. You may end up with issues when it comes to connecting these devices to “non-computer” equipment like printers or Blu-Ray players because they may present themselves as multiple USB devices which is something that these “non-computer” devices don’t really tolerate as I have raised before.

The SanDisk Connect Wireless Media Drive also uses an SDXC slot so you can use it as a place to “dump” your digital-camera images if you start to “run out of film” on your digital camera. Then you can either use it as a backup system for your holiday’s worth of photos during that trip or take some of the pictures further by uploading them to Flickr or Facebook using your laptop, smartphone or tablet. It also has higher storage capacity options in the form of a 64Gb variant as well as the 32Gb variant.

Personally, I would like to see someone take these devices further and do things like support DLNA or SMB/CIFS or provide network “annexing” as an option so they can do more than just being on the road. If not, we could start to see a very stale class of product come of these devices.

What about integrating NAS devices and cloud storage in desktop media-management software

There is a distinct reality that faces people who use regular computers as part of their personal or business media workflow. This is where they use the desktop media management software like iTunes, Windows Media Player, iPhoto or Windows Live Photo Gallery to curate the media collection that is on the hard disk but transfer it out to a network-attached storage device for safeguarding and continual avaiability. This could extend to us integrating content hosted on an online storage service like Dropbox or GMail.

This is being augmented by the trend with these devices effectively becoming the hub for our home media networks. But what happens is that we could do something like import photos from a digital camera or a smartphone; scan 35mm and Polaroid snapshots; rip content from optical disks or simply buy content from online services on a “download-to-own” basis, with all this content ending up on the hard disk. Typically the content is managed and curated on the regular-computer’s hard disk so as to provide fast and reliable data transfer through this process, before it is copied over the network.

But we have to make a routine out of synchronising the material that we prepare on our computers to the NAS and do this very frequently. Typically the task involves us synchronising the material using the file-system tools or third-party backup / file-sync tools. We then have to repeat this process if we update the metadata such as adding location and people tags to the pictures or simply reposition files to different folders.

Some of us may even adopt a storage strategy where we keep newer material on the computer while older material resides on the NAS. This may be done as a way to conserve the hard-disk space occupied by our media. Similarly, those of us who use laptops on the road may want the hard disks on these machines as a staging post for our media, whether to keep selected music or video content to have on the road or a temporary download point for our digital pictures like I did with the Acer Aspire S3 when I used it on my Sydney trip.

I would like to see an improved ability with media-management software to allow for integration of “off-system” resources as part of our media workflow rather than just a viewing location. This could be implemented with rules-based synchronisation that could work on a schedule, especially when we shut down the computer or put it to sleep. The file-modified test would be based on whether a file was new or had its metadata modified.

Similarly, it could be implemented through the positioning of a NAS or collection of NAS devices as primary storage locations while the local hard disk and online storage locations serve as secondary storage locations.

This may not just involve desktop media-management software but also involve working with file-synchronisation / data-backup software and data management software that is part of a network-attached-storage device or online storage service.

Product Review–Seagate GoFlex Home Network Attached Storage System

Introduction

I am reviewing the Seagate GoFlex Home network-attached storage system which I had first seen in action at the Australian Audio and AV Show at the Melbourne Marriott Hotel. Here, this unit was working as a DLNA media server for a small network that was to feed music to a Naim ND5 network media adaptor component.

Now, due to my WD MyBook World Edition network-attached-storage becoming full, I had wishlisted a network-attached storage device as a birthday gift and received this unit as a gift.

The Network-Attached Storage System itself

The Seagate GoFlex Home network-attached storage system is based around Seagate’s “GoFlex” detachable hard disk setup. Here, the hard disk is housed in a module that clips on to a connectivity base. This could allow people who have the smaller-capacity units to upgrade to larger-capacity variants by purchasing the larger-capacity disks. Similarly, one can easily replace a failed or damaged disk unit by buying the replacement GoFlex module and clipping it on to the base.

Setup Experience

The base that connects to the power and home network – USB, Gigabit Ethernet and power

Like most consumer NAS units, the Seagate GoFlex Home can be difficult to set up without the use of the software that comes on a supplied CD. This is although you can discover the NAS using the UPnP abilities in Windows XP onwards so you can get to the setup screen. The CD-supplied “Seagate Dashboard” software hasn’t been updated for Windows 8, so anyone running that software on this operating system will get an error message to that effect.

I was still able to work through the setup routine using the NAS unit’s Web interface but the Seagate required you to determine its own login parameters and couldn’t learn any existing login parameters that existed for other NAS units or network shares on the operating environment.

Seagate GoFlex Home NAS base

Where the hard disk module drops in to the base

The only time you can create a distinct identifier is through the setup process. This is reflected in the NetBIOS / SMV network name that is visible in the Network View for Windows. It is also reflected in the DLNA server list as <Network_Name>:UPNP-AV. Personally I would like to see this made available in the management menu so you can get the name right especially if you have multiple GoFlex Home or GoFlex Net devices on the same network.

Capabilities

The Seagate GoFlex Home uses the SMB / CIFS (Samba) method of sharing its disk resources which is expected as a standard with Windows, MacOS X and Linux.

For backing up your computers, there is the supplied Memeo backup software. But you can use your operating system’s backup software like Apple’s Time Machine or the Windows Backup for this task.

The supplied DLNA Media Server abilities have it that the media library is indexed by the date or the folders. There is the ability to have the DLNA server share particular folders in the Public tree which can be good for funnelling what appears on your Smart TV. This setup can improve the library-aggregation performance and reduce the number of confusing “non-media” files appearing in your media list that appears on that smart TV.

When you discover this NAS on your DLNA client device, the server appends “UPnP-AV” to the NAS’s name to remind you are looking at the device’s DLNA server and the media behind it.

You can also connect a USB hard disk or flash drive to the GoFlex and either use it as a destination for making a backup copy of what is on the NAS or simply to share extra data that is hosted on the external storage device across the home network. An example application of this could be share a USB hard disk which has the back issues of a classic magazine title like National Geographic across the network.

System performance

Nearly as small as a regular CD case

The Seagate GoFlex Home NAS yielded a consistent throughput of 500Mbps when transferring data from the existing WD MyBook World Edition to it. Of course, it is worth remembering that a connection’s rated speed like the Gigabit Ethernet’s capability is really the medium’s link speed.

For media streaming, I had observed that the GoFlex could yield a smooth and reliable experience with audio and video content. This was in both the experience with a similar unit at the Australian Audio and AV Show in 2010 and with this unit when I ran one of the “how-to” demo video found on this unit through our Samsung Smart TV.

As for operating noise, I had noticed very little of this even through the data transfer between the two NAS units. There was a bit of buzzing but this was due to a hard disk being active as data is being transferred to it.

Limitations and Points Of Improvement

Here, I would like to see Seagate implement simplified device naming, including access to this function in the setup menu. This would then apply to what it is known as in the “cloud”, on the network and via your DLNA-capable media devices.

As well. Seagate could implement always-available “public folders” that don’t need you to supply credentials to login. This can be useful if you are wanting to run this device as a “content pool” for drivers, PDFs and similar material or you need “non-computer” devices to gain access to a shared resource.

Like a lot of consumer network-attached storage devices, this could support “cloud-driven” NAS-to-NAS data synchronisation / backup. It could come in to its own with units located at secondary locations or as secondary storage for a business-tier NAS.

Conclusion

I would recommend that one purchases the Seagate GoFlex Home network-attached storage as either an entry-level network-attached-storage solution or a secondary network storage point for their home network. This could be as a simple backup solution, a file-transfer point, a communal file pool or for sharing media content to DLNA-capable devices.

Business users can see NAS units of the same calibre to this one work well as a DLNA media server for serving images or videos to a few endpoint devices, or simply as a secondary network file storage for less-critical files.

Outgrowing that NAS–what can you do

Seagate GoFlex Home NAS - an example of an entry-level NAS

Seagate GoFlex Home single-disk network-attached storage – an example of an entry-level NAS

As you outgrow an existing network-attached storage device that isn’t upgradeable, you may think of buying a newer higher-capacity NAS.

The older NAS is a secondary network data storage

This is something I have done lately as I outgrew the Western Digital MyBook World Edition’s 1Tb capacity and received a 3Tb Seagate GoFlex Home NAS as a birthday gift. Here, I was able to move my “work” data and system backups to the GoFlex while running the My Book World Edition as a DLNA Media Server for my photos and music. I could run either of these units as part of shifting data between two computers or run the My Book also as a data store for drivers, anti-virus, service packs and similar computer-service needs.

Spreading data storage across multiple units

Here, you don’t need to get rid of the older NAS, but run it as a secondary unit. For example, you could simply move most of the data like backup data or work-in-progress data off the older unit to the newer unit and run the older unit as a media server or simple data drop-off point. This can come in handy if you have to shift user-created data from that old half-dead laptop to that shiny new fast laptop before you retire it, or keep a collection of drivers and service packs for when you have to install new computers.

Separating business and personal data

In some cases, you could move business data to the newer NAS and have personal data on the older unit so you can segment the units easily for tax or corporate reimbursement purposes.

Your children and their data

The same situation can also be a boon for your teenage or young-adult child where they can keep their data and file-based media on the older NAS. Here, it then makes it easier for them to shift their data out with them when they grow their wings and leave the family nest. Here, they can use this device with a DLNA-compliant media player to play out their music at their new location as well as operating it as extra / backup storage space for their computer.

Media storage in another location

Similarly, you may be responsible for another small home network such as one at your vacation or seasonal home; or the “family house”. Here, the older network-attached storage unit could serve as the hub of a DLNA-based network media setup for this location with similar media content, especially music and video, at that location.

Auxiliary data storage at your small business

The small NAS that has been supplanted by your larger or more flexible unit can work as an auxiliary storage service for your small business. An example of this is to keep a small-business NAS working the mission-critical data with high security while you have the small NAS doing tasks such as being a DLNA media server in the context of a smart TV or Blu-Ray player providing cost-effective digital signage for your business.

Conclusion

Therefore it doesn’t mean that you have to retire that small one-disk network-attached-storage device when you outgrow it and buy a newer better unit.

http://youtu.be/-C1HAQj0YpQ – Link to this video if you can’t see it on this site or want to “throw” it to your DLNA smart TV using Twonky or similar software

My Comments

Previously, I commented on a news article about Sony releasing a NAS that allows you to upload pictures from your Android device just by touching the device to this NAS. Now, Sony have premiered this device along with another mobile NAS at Mobile World Congress in Barcelona this year.

But there are two devices rather than the one device. The former device that I touched on previously allows you to upload photos, videos and other content to its 1Tb hard disk using USB file transfer, NFC or SD memory cards so you can effectively “dump” your pictures and videos from your smartphone, camera or camcorder, thus making way for new material.

The Personal Content Station can play the images to a regular “brown-goods” flatscreen TV using an HDMI connector or you can make them available through your home network using the open-frame DLNA standards. I would also like to be sure that you can transfer the images between your PC and this device using standard network file-transfer protocols like CIFS or HTTP. Of course there is the ability to use an accompanying app to “throw” the images to a social network, blog or other Website using your smartphone or tablet.

As well, the Portable Wireless Server can share the content you have on a USB storage device or an SD card to its own wireless network so you can quickly share “just-taken” photos with your smartphone, tablet or Ultrabook. This is becoming important with devices like the Dell XPS 13 which doesn’t come with an SD card slot or the detachable-keyboard hybrids that have a standard SD card slot only on the keyboard module.

The Sony Portable Wireless Server also works as an “external battery pack” for the many battery-thirsty gadgets that are important to our mobile online life. This is so true if you are dealing with the smartphone that serves as your mobile Internet terminal or your Walkman.

At least Sony is fielding devices that work as a team to satisfy the reality that confronts us through our online content-creation lives.

Sony’s Personal Content Station uses NFC for mobile backups, aims for April release in Japan

My Comments

I was impressed with the Sony Personal Content Station which is an elegant ceramic-white device that works as a 1Tb mobile NAS for your mobile devices and, perhaps, your home network.

One feature that stands out is to be able to use NFC-based pairing to permit device-to-NAS file transfer between an NFC-equipped Android handset or tablet and this device. Of course, it works as a Wi-Fi NAS for other devices and you can of course upload from a USB-connected device or dump the contents of your SD “digital film” card to this device.

There is the ability to show the content on a TV whether directly-connected via HDMI or via a DLNA network connection. Of course, a good question worth raising is whether the Personal Content Station could interlink with an existing home network as a media server / NAS or simply be one of many devices of this ilk that are their own network. This includes whether a Wi-Fi Direct transfer could occur while the Personal Content Station is connected to the home network.

Another question yet to be raised is whether “other” NFC-initiated Wi-Fi-Direct file transfer software like Samsung’s S-Beam could do the file-transfer job without the need to install Sony’s software. This could avoid the need to “crowd out” an Android phone with many of these apps to suit different devices. Similarly, I would prefer this device to support any DLNA “media-uploader / media-downloader” standards so you can move content between this device and similar devices; and your mobile handset or digital camera via Wi-Fi by using one piece of software.

Using a NAS to hold operating-system updates

The current situation

Netgear ReadyNAS

A network-attached storage can come in handy for storing software updates rather than downloading them frequently

Operating system and application developers are now being required to provide updates for their products during the product’s service life and beyond. This is to provide for a computing environment that is performs in an efficient, secure, reliable and optimum manner. The updates may be released at regular intervals such as on a monthly basis or in response to a situation such as the discovery of a bug or security exploit.

New devices

A common situation that happens with most regular and mobile computing devices when a user takes delivery of them is that the user downloads a large data package to bring it up to date. This may be done many times if multiple units running the same platform are purchased.

Many devices

Similarly, a household may have multiple units running the same operating environment and they have to keep these up to date. The typical example of this may be a family with two or three children who are at secondary school. Here, they may have two or three computers for the children to use as well as one computer per adult. This could be brought about with the older child being given a more powerful computer as they enter senior high school or another computer given to the younger children as they start their secondary school.

But the same bandwidth would be used again and again to update each and every device. This may not be a problem for a couple with one device per adult but would be a problem when you are thinking of environments with more than two devices which is fast becoming the norm.

Using a network-attached storage to locally cache updates

Somehow the network-attached storage devices need to be able to support the ability to locally hold updates and patches for operating systems and applications used in computers on a home or small-business network.

The practice is performed frequently with large-business computer setups because of the number of computers being managed in these setups. But it could be practiced with home and small-business setups using a simplified interface. This could be based on the use of a local-storage application for regular or mobile client operating environments which supports this kind of local updating.

A local client application to manage system-update needs

Here, the local-client software could register which operating environment the host computer runs and what eligible applications are on the system so as to prepare an “update manifest” or “shopping list” for the computer. The “shopping list” would be based on the core name of the software, no matter whether different computers are running different variants of the software, such as home laptops running Windows 7 Home Premium while a work-home laptop runs Windows 7 Professional. This manifest would be updated if new applications are installed, existing applications are removed or changed to different editions or the operating system is upgraded to a different version or edition.

A local software manifest held by the NAS

This manifest is then uploaded to the NAS which runs a server application to regularly check the software developers’ update sites for the latest versions and updates for the programs that exist on the “shopping list”. There could be a “commonality” check that assesses whether particular updates and patches apply across older and newer versions of the same software, which can be true for some Windows patches that apply from Windows XP to Windows 7 with the same code.

At regular intervals, the NAS checks for the updates and downloads them as required. Here, it could be feasible to implement logic the check the updates and patches for malware especially as this update path can be an exploit vector. Then the computers that exist on the network check for new software updates and patches at the NAS.

Software requirements

Such a concept could be implemented at the client with most regular and mobile operating systems and could be implemented on network-attached storage devices that work to a platform that allows software addition.

It would also require software developers who develop the operating systems and application software to provide a level of support for update checking by intermediate devices. Initially this could require setups that are particular to a particular developer being installed on the client device and the NAS, but this could move towards one software update solution across many developers.

A change of mindset

What needs to happen is a change of mindset regarding software distribution in the home and small business. Here, the use of local network storage for software updates doesn’t just suit the big business with more than 50 computers in its fleet.

It could suit the household with two or more children in secondary school or a household with many young adults. Similarly a shop that is growing steadily and acquiring a second POS terminal or a medical practice that is setting up for two or more doctors practising concurrently may want this same ability out of their server or NAS.

Conclusion

The NAS shouldn’t just be considered as a storage device but as a way of saving bandwidth when deploying updates in to a household or small business who has multiple computers on the same platform.

Creating a small data cloud–why couldn’t it be done

The small data-replication cloud

Netgear ReadyNAS

These network-attached storage devices could be part of a personal data-replication cloud

Whenever the “personal cloud” is talked of, we think of a network-attached storage device where you gain access to the data on the road. Here, the cloud aspect is fulfilled by a manufacturer-provided data centre that “discovers” your NAS using a form of dynamic DNS and creates a “data path” or VPN to your NAS. Users typically gain access to the files by logging in to a SSL-secured Web page or using a client-side file-manager program.

But another small data cloud is often forgotten about in this class of device, except in the case of some Iomega devices. This represents a handful of consumer or small-business NAS units located at geographically-different areas that are linked to each other via the Internet. Here, they could synchronise the same data or a subset of that data between each other.

This could extend to applications like replicating music and other media held on a NAS to a hard disk installed in a car whether the vehicle is at home, at the office or even while driving. The latter example may be where you purchase or place an order for a song or album via the wireless broadband infrastructure with the content ending up on your car’s media hard disk so it plays through its sound system. Then you find that it has been synchronised to your home’s NAS so you can play that album on your home theatre when you arrive at home.

What could it achieve?

An example of this need could be for a small business to back up their business data to the network-attached storage device located at their shop or office as well as their owner’s home no matter where the data is created.

Similarly, one could copy their music and video material held on the main NAS device out to a NAS that is at holiday home. This can lead to location-specific speedy access to the multimedia files and you could add new multimedia files to the NAS at your holiday home but have this new collection reflected to your main home.

Here, one could exploit a larger-capacity unit with better resiliency, like the business-grade NAS units pitched at small businesses, as a master data store while maintaining less-expensive single-disk or dual-disk consumer NAS units as local data stores at other locations. This setup may appeal to businesses where one location is seen as a primary “office” while the other location is seen as either a shopfront or secondary office.

This kind of setup could allow the creation of a NAS as a local “staging post” for newly-handled or regularly-worked data so as to provide a resilient setup that can survive a link failure. In some cases this could even allow for near-line operation for a business’s computing needs should the link to a cloud service fail.

User interface and software requirements

This same context can be built on the existing remote-access “personal cloud” infrastructure and software so there is no need to “reinvent the wheel” for a multi-NAS cloud.

Similarly, users would have to use the NAS’s existing management Web page to determine the location of the remote NAS devices and the data sets they wish to replicate. This can include how the data set is to be replicated such as keeping a mirror-copy of the data set, or contributing new and changed data to a designated master data set or a combination of both. The data set could be the copy of a particular NAS volume or share, a folder or group of folders or simply files of a kind.

The recently-determined UPnP RemoteAccess v2 standard, along with the UPnP ContentSync standards could simplify the setup of these data-synchronisation clouds. This could also make it easier to provide heterogenous data clouds that exist for this requirement.

But one main requirement that needs to be thought of is that the computer systems at both ends cannot collapse or underperform because the link fails. There has to be some form of scalability so that regular small-business servers can be party to the cloud, which may benefit the small-business owner who wants to integrate this hardware and the home-network hardware as part of a data-replication cloud.

Hardware requirements

A small data cloud needs to support cost-effective hardware requirements that allow for system growth. This means that it could start with two or more consumer or SME NAS devices of a known software configuration yet increase in capacity and resilience as the user adds or improves storage equipment at any location or rents storage services at a later stage.

This could mean that one could start with one single-disk NAS unit at each location, then purchase a small-business NAS equipped with a multi-disk RAID setup, setting this up at the business. The extra single-disk unit could then be shifted to another location as a staging-post disk or extra personal backup.

Conclusion

What NAS manufacturers need to think of is the idea of supporting easy-to-manage multi-device data-replication “personal clouds” using these devices. This is alongside the current marketing idea of the remote-access “personal cloud” offered for these devices.

Western Digital now launching NAS-optimised hard disks

WD Has New Drives Designed For Your NAS ! SmallNetBuilder

From the horse’s mouth

My Comments

Netgear ReadyNAS

Now there are some hard disks optimised for NAS units like this ReadyNAS “music server”

Western Digital have released a range of hard disks that are optimised for the common network-attached-storage device. You may think that you need to use a regular desktop hard disk for this application but the WD RED range can suit this space in a more reliable manner.

These 3.5” SATA HDDS are set up for 24/7 operation yet have reduced power needs. Their software even is optimised for this class of device by assuring quick response and high compatibility across most NAS enclosures. But I also would reckon that they would suit those large USB / eSATA hard-disk subsystems that are commonly used with USB file server devices like the Freebox Révolution or one that was part of a home network that I helped someone with.

Compared to a desktop or mobile hard disk that has to deal with reduced duty cycles or a high-end server hard disk that is optimised for intensely-active corporate servers with large power allowances and many-spindle disk arrays, these are optimised for a small NAS that has a small power supply that provides power to up to five spindles.

WD aren’t just selling these 1Tb-3Tb hard disks with their MyBook Live NAS products but making them available as disk units for use with diskless NAS or USB enclosures. This also applies to those of us who buy a multi-bay NAS enclosure like a NETGEAR ReadyNAS with one disk, then add hard disks to this enclosure as needs, funds and time allow.

They also have support for proper AV streaming which would be required of most NAS subsystems used in the home as DLNA Media Servers or “NVR” subsystems used in small-business IP-based video-surveillance setups. This would cater for a glitch-free audio or video recording and playback experiences.

A good question I would ask is whether the competing manufacturers like Fujitsu and Seagate would answer WD when it comes to providing the hard disks optimised for these small network-attached-storage systems.
