I have a DDS-4 drive, 20GB capacity but I can get a little more than that
with hardware compression. They bill it as "20/40" but obviously the
compressed capacity depends a lot on your data. It works pretty well; it's
surprisingly fast. I don't normally wait for it -- I just switch the
tapes and the backups happen later at night; each backup is under 25 GB so
I don't have to switch the tapes mid-backup. (I don't have a changer.)

The drive I have is SCSI (Python 06240-XXX according to the kernel) just
works... no configuration was necessary, other than setting the SCSI
ID. I think the DDS-4 is perfect for my situation -- the tapes are
decent capacity at 20 GB, and aren't too expensive at about $30 each.
As I think I mentioned elsewhere, I use the Arkeia backup software, which
works well for me but isn't free for larger than a small installation.
