The ST-4096 is a well-established decent performer which is now available for
excellent prices. Many folks have used them on cheap file servers.

The ST251/277 suffer from a Seagate design flaw which started in 1987 when
they started producing their own magnetic media. As a result, the heads
sometimes get "Stuck" in a glob of lubricant when you power the drive down.
This is called "Stiction" and is an excellent reason not to buy a recent
vintage ST251/277.

Both drives are self-parking on power-down. They use different means
of doing it, but they both self-park.
