14 DAY TRIAL // Most network-attached storage devices I cover usually come in blocky, HTPC-shaped cases, since those are the ones that consumers are likely to buy, but there are other types, like the one Synology just released.
Called RS814+/RS814RP+, it is a 4-bay NAS featuring the 1U form factor, the same shape usually employed by blade servers.
Then again, considering that the NAS is basically going to steal the job (or potential job) of servers, that's not so shocking.
Besides, the form factor is much better suited to businesses, since it is also scalable (stackable too).
DiskStation Manager (DSM) 4.3 is the software that runs it (operating system really).
In a Windows environment, performance is of over 330 MB/s read and 196 MB/s write under RAID 5 configuration, thanks to the 2/4 GB DDR3 and 2.13 GHz dual-core processor.
