Summary: This has been a good tool for *slow* backups. Tried to do a longer file copy and the throughput was a little over 1 Mb/sec on a 1 Gb link with 1 hop on a 1Gb switch. The NAS was configured in Raid0, which I think is as fast as it can get. Everything else about it has been fine and fairly intuitive, but I agree w/the "Don't be Buffalo'd" review. This is NOT a speedy NAS, and at 1 Mb/sec on a Gb link it's pretty safe to say it's SLOW.
Summary: This is actually my third Buffalo NAS the first two being LinkStations. Both LinkStations had bad fans and one hard drive failed within days of installation. I decided to try a TeraStation hoping it would be more reliable since it is a business class NAS (It is also much more expensive). It is more robust and has a much better fan. It also has more bells and whistles but that is not what drove me to upgrade.
