Any SCSI tape drive will work nicely with FreeBSD. We have
a few different levels of DAT DDS-2, DDS-3 and DDS-4 as well
as DLT and LTO drives in various systems - all on SCSI.
Dell sells DLT and DAT. HP is pushing LTO (they call Ultrium).
The DLT and LTO performance are all outstanding.
If you do frequent backups (recommended) I would steer away
from the DAT (DDS...) because they really can't handle the
heavier usage. Reliability becomes a problem over time.
On some other systems we also have AIT drives working well but I
haven't used them on FreeBSD yet.
Unfortunately the DLT and LTO drives are rather expensive.
But the high speed and reliability will be worth it in
the long run.
As for software, we just use dump(8)/restore(8).
