  As I noted before, that was a typo, the low (fragmented) rate was
300KB/min (not /sec), when the disk is not fragmented and the tape
streams the rate is 4MB/min (there I typed it right twice).

  That's fine for my 180MB now, but when I add this 320MB drive on the
table here, it is going to be a pain. The rates are fast enough, but the
tapes are too small...
