Buffalo Technology 1TB TeraStation

Buffalo Technology may have a solution for inexpensive RAID-1 or 5.

4 250GB hard drives, works with both Mac and PC platforms, and has Gigabit Ethernet, and a USB 2.0 port if
you want to connect directly to your computer rather than access it over the network.

I want to get one to try for a DIY network storage device…
