Thanks very much for all the leads I received after
posting this yesterday.
We have received very positive, good bids, and, and,
and, I might be adding close to terrabyte of space
(910GB) soon. Thanks to all once again.

EXTRA QUESTION: If you happen to see it:
We have 9.1Gb drives on an HSZ50 controller, do you
know if that can handle 18.2 Gb drives? What are the
limitations?

Another tip(not sure if it would interfere with
maintanance contracts):
I was recently buying several 18.2Gb hard drives
(SN-PBXRW-TB) Compaq.
There was some mix up with part numbers, so it took
quite a long time for our suppliers to source them.
Meanwhile I looked at the labels on existing drives
and found that they have Fujitsu part numbers on them
as well as Compaq part numbers. Equivalent to the
above was MAH3xxxMP.

So I went to Fujitsu shop and they have drives for me,
but not MAH, but MAJ. The only difference was speed,
it was 10000rpm instead of 7200rpm.

Fujitsu guy told me that they are 100% compatible.
Obviously they are, because they work just fine now on
our stations. And they cost almost twice less for us.
There was no need to change firmware, though it could
be different in your case.
