The D-Link DNS-323 2-Bay Network Storage Enclosure enables users at home or in the office to share documents such as music, photos and videos across the network and on the Internet, so family members, friends, or employees can gain access to them. In the office, this enclosure also provides a central network point to back up valuable files and protect them from drive failure by using the built-in RAID 1 mirroring technology. At home, this device can be used to stream music, photos and videos to UPnP AV compatible network media players.
Opened a new thread for this as a) the original Dabs thread was expired, resubmitted at a higher price, and they have no stock at present; b) this is also cheaper than the BT Shop deal.
Free shipping for those prepared to wait for up to 5 working days, although the last one I ordered only took 3.
Over 180 available at the time of posting. The last batch sold out quite quickly so probably wouldn't wait too long if you were considering purchasing.
