Tag: Seagate GoFlex Home

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 removable hard disk module

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.

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.

Introduction

Netgear ReadyNAS as a music server

A new class of hardware has been brought about by the networked home and small office environment. This is in the form of the network-attached storage device which works simply as a hard disk that is attached to the small network, sharing its resources using common network protocols.

Description

A network-attached storage device or NAS is an appliance that connects to your home or small business network via Ethernet to serve as a communal storage device for that network. This is instead of purposing an older computer for this role of a common storage device.

One main advantage of these devices is that these devices don’t demand as much power as a regular desktop computer running as a server and they make less noise than the typical ATX desktop tower computer. Therefore they need less power to run and don’t need to have a constantly-running fan. This also leads to a device that is quiet and energy-efficient, values that are being asked of in this era.

The devices are typically very small, often ranging in size from a pair of cassette tapes through a small book to the size of a kitchen toaster for the small-business units.This means that they don’t take up much desk space and can even be hidden behind other computing devices, which also puts them in the good books with those who value aesthetics. This small size also wins favour with those of us who want a data storage to serve multiple devices but that can be quickly shifted to a location at a moment’s notice; as I have seen for myself at the Australian Audio and AV Show with a few of these devices working as DLNA-compliant media servers for demonstration hi-fi equipment. Infact the pictures of the Netgear ReadyNAS and the Seagate GoFlex Home NAS units are images of fully-operational units serving this aforementioned role, with the Seagate single-disk unit being photographed on the floor and it being slightly higher than the skirting board.

Disk Storage

Single-Disk NAS

Seagate GoFlex Home single-disk NAS

Cheaper consumer-focused NAS units are typically equipped with one hard disk with a few of these units like the Seagate GoFlex Home being a network bridge for a removeable hard-disk module that is part of the manufacturer’s modular-hard-disk system.

This also includes the portable NAS units like the Seagate GoFlex Satellite that are their own Wi-Fi network and are intended to work as a data offloading device for tablet computers.

But on the other hand, there are some single-disk NAS units like the QNAP range that can excel as highly-capable network storage hubs. In the case of the QNAP, these units are able work as full-flight Web servers suitable for serving intranets or “proving” Web-site prototypes; or pull off other advanced network-storage tricks.

Multi-Disk NAS

On the other hand, the better units will support two or more hard disks which work the installed hard disks as a RAID (Redundant Array of Independent Disks) that facilitate either extra capacity, higher data throughput or increased fault tolerance.These multi-disk units can be set up to have two hard disks of equal capacity “mirroring” each other as a safeguard if one disk fails or to facilitate high-throughput low-latency data transfer. On the other hand,the disks can be seen simply as a large volume of data. Units which support three or more disk drives can support disk setups that combine failsafe data storage and increased data capacity.

Some multi-disk units like the Netgear ReadyNAS units have the ability to support in-place volume expansion. This is where you can add extra hard drives to the NAS while it is running in order to build up redundant failover storage or increase system capacity. But other systems will require the NAS to be taken out of service if you intend to evolve the multi-disk RAID volume.

User-installed disks and upgrade options

Most of these NAS units have the hard disk integrated, which is at a known capacity whereas others, commonly known as BYOD enclosures, come simply as an enclosure where you buy the hard disk separately and install it yourself. A variety of multi-disk units do come with a single hard disk but you upgrade them to the RAID resilience or extra capacity by installing a hard disk in an empty disk bay. This kind of installation typically can be done without the need for tools in all of the recent implementations.

Of course, the cheapest single-disk NAS units don’t allow you to upgrade or replace the hard disk yourself, so you have to replace the unit if that hard disk fails or you outgrow the hard disk capacity. On the other hand, the better units permit the user to upgrade or replace the hard disk, thus providing for a long device lifespan.

External connection ports

A lot of NAS units have one or more USB ports so you can copy content off a thumbdrive or external hard disk, use an external hard disk as extra storage or a backup device for the NAS or use other peripherals. Some of them may use an eSATA port for the same purpose, especially to add storage or maintain a backup device.

It is also worth knowing that these ports may be used as a way of extending the functionality of the NAS devices through the use of various device classes; especially if subsequent firmware upgrades take place. Example applications include working as a print server for a USB-only printer to a camera server for a Webcam.

Functions

Network-central backup location

Most network-attached storage devices typically provide the ability to be a network-central backup device for all of the computers in that network. This is typically facilitated through manufacturer-supplied software or backup utilities that are part of a regular-computing operating system such as Windows Backup or Apple Time Machine.

Network-central file storage and drop-off point

They also work as a data-drop-off point where users can “park” redundant data or data being moved between computers and hard drives. This is facilitated using standard SMB/CIFS, FTP or HTTP machine-to-machine data transfer protocols which these operating systems can support natively. The computer may run a manufacturer-supplied “assistance” shell to help with locating the device or linking it to the computer.

In the same extent, the NAS may work as a shared data library for software and data that is needed across the network. This would include utility software, device drivers, updates and patches as well as documents of common interest.

It is being extended to mobile computing devices like smartphones and tablets through the use of manufacturer-supplied or third-party network-file-transfer apps for the common mobile-computing platforms like iOS or Android. I have covered this topic in an article about moving data between your NAS and your smartphone.

Media server

This now covers the ability to share media files like digital images, music and video files to every computer and DLNA-compliant media device across the network.  This is facilitated through an integrated DLNA media server for standards-compliant devices and an iTunes-compatible server for iTunes media managers including Apple iOS devices.

But some manufacturers are targeting some of their consumer-focused NAS units at the distribution of media files across the network. These will typically have software that provides for low-latency transfer of audio and video content as well as an improved DLNA media server. Some of these DLNA media servers may support content-metadata aggregation where they index all media held on every DLNA server in the network and become the single point of reference for that media.

Some of the NAS units like RipNAS, ZoneRipper or Naim UnitiServe may even have an integrated optical drive to allow you to “rip” CDs to the hard disk or allow you to connect an optical drive to their USB port so you don’t have to power up a computer to “rip” new CDs to your media collection.

Remote access and the personal cloud

A new capability that is being promoted by NAS vendors such as Western Digital and Iomega is remote access, commonly marketed as a “private cloud” or “personal cloud”. This requires the NAS to have server software that exposes its location to a cloud service on the Internet and manage access to the data from Internet-based users. It works alongside client software available for regular or mobile operating systems to enable users to transfer the data outside their home network.

Variants of this software, such as what Iomega offer, may support peer-to-peer data transfer between multiple NAS units installed at different locations. This could cater for multi-site content replication or simple offsite data backup requirements.

Platform NAS systems

An increasing number of high-end NAS units have the equivalent of an app store, where the manufacturer can provide free or paid file-handling programs that load on to these devices. These can include a simple photo-viewing intranet app, a DVR for video-surveillance apps, an email server or a download / Bittorrent manager amongst other things.

Some systems like the QNAP units deliver every function in one “hit” when the user purchases the NAS devices whereas others just maintain the “app-store” or “download-point” for users to add the functions on at a later time.

What should you get

A single-disk NAS can serve a typical household well as a data drop-off point and media server. It can also augment a small-business’s server by fulfilling low-risk tasks such as DLNA media-server functionality thus keeping the server for business-critical needs. The high-end varieties of these single-disk NAS units like what QNAP sells would work well for those of us who want more functionality such as a Web-development workbench or a DVR for an IP-based video-surveillance system.

If you end up with more devices in your home and you want to be sure of continuity or expandability, a multi-drive system would fit your bill. You may go for a multi-disk system that has one hard disk installed so you can upgrade to resiliency or extra capacity at a later time.

Small businesses should consider a good multi-disk MAS that has what it takes to support increased resiliency. In some cases, a small business may operate the multi-disk NAS as a backup or file-archive device for their site’s main operational server; as well as a media server or similar application.

It is also essential to look at an offsite backup option for these units, such as the ability to connect a USB external hard drive for the duration of a backup job or the ability to backup to another NAS or cloud service via the Internet.

Mandatory features

For basic functionality, the NAS should support the SMB/CIFS and NFS network file protocols and have an integrated DLNA and iTunes media server. The computer-NAS backup options can be hosted with manufacturer-supplied software bout should work with Windows Backup or Apple Time Machine options.

I would also prefer that the NAS supports a continual software upgrade path for its functions. This is where the manufacturer keeps the firmware up to date as new standards come about, thus opening up the door to newer functionality and better performance.

The connection to the networks should be at least one Gigabit Ethernet port in order to support higher data throughput. You may not get this throughput with your existing router but if you upgrade to a newer router that has Gigabit Ethernet ports, you will end up with significantly higher throughput which would benefit applications like movies or high-quality music files.

Conclusion

Once you have a network-attached storage device in place, you will never know what capabilities these devices will open up to the connected home and small business. It doesn’t matter whether it’s a backup location for your computers or a media server or just simply a “file parking lot” for your home network.
