 I am afraid you're wrong. I saw Seagate drives (in older stations) and,

SGI used to use Seagate exclusively (up to a year or so ago), but then

go to Quantum for a short period, but they found that the Quantum drives
have a nasty habit of recalibrating themselves from time to time, which

performance hit on these machines.  Quantum was unwilling to rewrite the
firmware on their drives, so testing continued.  IBM drives are the only
ones that currently meet SGI specs.

This was from a conversation with an SGI tech about three weeks ago.

Which Seagate/Quantum drive was using and which IBM drive is using by
SGI?

I don't have that info.  You'd have to ask SGI.

Thanks for the correction. Not that it helped a whole lot, by the way, 
after the infamous patch 466 disaster with IBM Ultrastars.

-  Received message begins Here  -

I looked at a new drive and the only thing I saw was a DHFS sticker from
IBM. Is that a model number or something?

As far as the Seagates, I saw a couple of ST43400ND drives here in the
office.  They appear to be 2-3 years old.  I don't know of any others in
use by SGI for sure, but I'd guess there are others.  The 43400 is 
a bit too big to fit into an Indy.  I don't have an Indy torn appart 
to look at right now.

In an attempt to avoid a war, I'll simply say that Silicon Graphics is
using IBM SCSI drives exclusively.  Given the nature of their products, I
doubt that it's because of cost.  (Actually, it's because IBM drives give
the best _consistent_ performance.)

I am currently using Quantum GP and it is very noisy.  I looked
at the Web and found that IBM is cheaper then Quantum, while
seagate is the most expensive one (more than $200 over Quantum).
