 * Many recent Seagate drives are okay, but when I have the choice, I pick
 * IBM over Seagate.  This has as much to do with reliability as with how
 * well behaved SCSI protocol wise, the IBM drives are.  Their firmware is
 * rock solid and their reliability numbers leave Seagate in the dust.

I don't know about that.  The IBM DCHS ("Scorpion") drives have been
nothing but problems for us, and need a lot of schmoozing to get them
to work under pressure without locking up.  (And I'm sure you know
that too, because it's you who helped me get them run. :)

As far as manufacturing quality (not firmware) goes, IBM drives are
pretty good.  We've had ~400 in our systems for about a year and only
one has died outright so far.
