I am using a Seagate (formerly Conner) TS8000 at home and a TS4000 at work
- 8MB and 4MB respectively.  They are really the same drive, the 8000
accepts the Travan cartridge format.  These are SCSI-2 devices, and use a
"wide QIC" tape.  The mfr. claims up to 50MB / min. x-fer rate, but I have
seen 20MB maximum, with 10-12 more the average over the ethernet.  This is
with 32bit (Buslogic) bus mastering controllers.  The TS4000 does daily
backups of a 1G Novell server, and has been in service for approx 2.5
months.  I have used the 8000 to backup (tar) and restore Redhat 4.0, with
no problems to report.  At approx. $325 for the 4000 and $369 for the
8000, I think these are very economical choices, competitive with the hard
drive alternative.  The 4G cart's (1.86 non-compressed) retail for $30, 
the 8G for $40.
