Summary: Tech support also does not respond, i've been waiting 3 days for a response with nothing so far. I would avoid this unit.
Pros: It's cheap
Cons: I purchased two of these devices to be used to store backups coupled with Western Digital Black 1TB drives. The backup product makes a MD5 hash of the data before sending it to the NAS. On both devices in different sites I have seen file corruption problems where the data fails MD5 verification.
Summary: It appears that the nsa310 is not supplied with the memeo backup software that is mentioned in some reviews. It has facilities for backing up the device to another network storage device and for backing up usb sticks. Howevever, there do not appear to be any facilities for backing up a local PC. The device appears to be a good cheap media server but this lack of backup software is crucial.
