I've never had good luck with these low powered CPU/Unix NAS drives, they typically have poor performance even very low read/write speeds etc but the speed on this one seems "OK" (still half the speed of a PC mounted drive).

As a backup it may work well as with a separate device you have the ability to cover:
- Theft, Fire, Catastrophic HW Failure etc of your main data store
- Protection from inadvertent changes, deletion of files on the main data store (I use FreeFileSync to first preview then sync all my media from the main to the backup node.)
Nothing beats backup!
FYI - my setup are two 30TB nodes, one is a pretty high speced Main PC (Win 8) that acts as the media server, and the other a WHS box that backs up all the PC's in the house ever day (incremental) and to which I manually sync content. It has saved me heaps of times.

Actually, their results seem to have been debunked somewhat. Personally I don't like Seagate drives - especially now that they own Maxtor, but there seem to have been a number of external factors that could have affected these results.

I use Dlink raid1 enclosures, either the quad or dual drive models. Buy them bare for pretty good $$, then fill them with good drives as I find them on sale.
The newer ones have USB3 and gigE connections than can be run at the same time.
There are other makers that make raid enclosures that connect via eSATA as well as USB and ethernet.
Remember that with external drive enclosures you don't have to buy 7200 or 10k rpm drives. The throughput of the connections, gigE or USB3, isn't enough to even come close to saturating 5400 rpm drives.
Also remember that direct-connected (SATAor eSATA) drives will almost always be faster than USB or ethernet connected drives.
