My boss bought a Western Digital MyBook World Edition with 4TB (2TB in RAID1) for use as a backup device so we can free up some of our expensive SCSI drives. For $600, this is a decent buy. While it is set up for Windows, it runs Linux and has sshd set up so you can enable it via the web interface. While rsync v3 is installed, some other utilities are not, so it is best to install optware to get things like rsnapshot, sudo, and a decent cron. However, it is slow. I am seeing about 6GB/HR, so it works fine as a backup device because rsnapshot uses rsync with the --link-dest flag, so subsequent backups transfer only incrementals. However, I would NOT recommend it as an NFS or SAMBA server unless you really want to enforce speed limits on your network :-)
