The machine is solely dedicated to Amanda.  It is doing nothing else. 
This drive is in an HP StorageWorks MSL5026S2 library, connected to an
LVD SCSI bus (80MB/s), so there should be no bottleneck there.  The
host's disks are on a separate LVD channel.  The buses are terminated
properly-- dmesg shows no SCSI errors.

After disabling H/W compression, I am getting the same performance from
tapetype.  It has been running for 15 hours and has only written about
30GB.

What are the consequences of having the wrong values in a tapetype
definition?  If the size value is too large, Amanda will just encounter
EOT sooner than expected, right?  If it's too low, you waste some tape. 
I'm thinking I might take what people have already posted for the DLT220
drive and scale it up by 45% (160 is 45% more than 110).  Am I crazy?
