this is an older, superseded NAS - no USB3, but still has gigabit ethernet, bittorrent server and android/ios apps.
a very good basic nas for $79 - next cheapest on staticice is $130.

apparently it can take 2 x 3TB drives.
Damn, I was hoping I could wait until the end of the week before this one was discovered!
It's a great unit, I have one and have ordered one for the parents as it's reliable and simple (once set up)
Set up IS a pain though so be prepared for some frustration.
