I would have to say that a drive's transfer rate make more of a difference
than the average access time. Unless you are doing intensive database work
which requires a lot of seeks or you have a badly fragged hard disk, the
transfer rate will make more of a difference. Compare a ST506/412's
5Mbit/sec to something like an Imprimis 94181-702M's 15-24Mbit/sec (ain't
sure on this one but it's somewhere in that neighborhood). The Imprimis
will just blow your socks off.

I have not used the SyQuest 10MB cartridge drives but I have used the 44MB
cartridge drives and find them to be quite reliable. Sure, you wouldn't
want to risk a cartridge by dropping it two feet but then again, would you
do the same to your fixed hard disk? The SyQuest 44MB drives are
auto-parking so power failures have little effect. They also work well on
their sides. Look at PLI's 44MB drive. They are suppose to work on their
sides!

I am putting together a 44MB drive for a friend this weekend. Will report
on how it runs on the ST. Should be fairly decent in any event.
