My comments on this “midget” NAS
The 2.5” laptop hard disk as part of a highly-portable dual-drive network-attached storage has matured as a form factor with Thecus competing with Buffalo Technology in this product class.
The reason that these network-attached storage devices, which would be nearly the same size as a regular single-drive unit that works with a 3.5” hard disk is that they can offer what the what the regular single 3.5” hard disk units offer but with more advantages like reduced power consumption and operating noise as well as the advantages of being able to work as a RAID device.
The Thecus NAS has improved on the Buffalo design by offering BitTorrent support and the ability to work with a USB webcam as a time-lapse video recorder / network camera server as well as the usual file storage and DLNA media-server functionality.
As more companies sell these small dual-disk NAS boxes that use laptop hard disks, this could open the floodgates for network data storage applications where size or reduced power and operating-noise matters. It doesn’t matter whether you are dealing with
Point of innovation
An opportunity for innovation that can exist with this class of NAS devices is for them to work on an automotive or marine power supply environment. This is a power supply which runs nominally at 12 or 24 volts DC but would typically have varying-voltage conditions due to situations encountered in these situations like whenever the engine is started. These units would also need to shut down if the power is below a critical level for vehicle use so the engine can be started. As well, it may be desirable to support “ignition sense” so the unit can go in to different operating modes depending on what position the vehicle’s ignition switch was set to.
If this is achieved, these NAS devices could provide data storage to an in-vehicle LAN (which may have a wireless wide-area-network router at the edge) in a cost-effective manner. It could then lead to DLNA-based media handling on the road and improved network-based local data storage for “office-on-wheels” applications. With the Thecus NAS mentioned in the article having USB webcam support, it could allow for the use of a cost-effective USB webcam-based “black box” video-surveillance system for mobile applications like, for example, buses operated by community organisations and schools; or delivery vehicles.
At least there are signs of progress towards the small-form-factor NAS boxes becoming a reality and increasing the application space for these devices.
