My client had been using a TeraStation 1Tb as the main file server. It works as advertised, but after 18 months it died, the unit shut itself down and when we restarted it, it can no longer connect. Since it is out of warranty, Buffalo will do nothing for us, NOT EVEN SELL US A REPLACEMENT CORE. They offer no extended warranty, although the support supervisor was kind enough to call Austin HQ with the problem, they still won't budge. So if you are considering using this as the main file server, or any Buffalo product in a crirtical business application, BE WARNED.
