The next step in $WORK's continuing quest for cheap semireliable storage is complete. Yesterday FedEx delivered two Buffalo TeraStation 1 TB NAS devices. They're cute, with red, blue, and green blinkenlights. Easy to set up through a web interface. I've configured them as RAID 5, so that's 750 GB each. So far, so good.
Unfortunately they don't seem to be very hackable. They run Samba and an NTP client and FTP (if requested) and the web interface and not much else. No ssh, telnet, rsync, apparently. There's Linux in there, but it's not accessible. No ports on the box other than USB and a serial port for attaching a UPS monitoring cable. Of course, minimality is part of the point.
