I got some older SCSI HDs from a yard sale a while ago. The condition of
other equipment purchased from this sale was good. I am confident that
these drives are ok, so I'm going to take a chance on buying a controller
card.
The Drives are:
1) WD Enterprise WDE 9100 9.1 GB Single-ended Ultra Fast Wide SCSI-3
Interface
2) WD Enterprise WDE 9180 9.18 GB Ultra2 LVD SCSI
I have never setup SCSI drives before. Here is what I know about SCSI: NOT
MUCH! (Except what Garl said about speed and reliability, etc.)
Compared to a modern SATA drive, these will not be that fast. Compare a
modern 10k SATA drive against with NCQ against a modern 10K SCSI drive,
and they should be about the same, in most desktop conditions. The big
difference comes when you put multiple drives together, when you put a
10k or 15k SCSI drive against a 7.2k SATA drive, or when you start doing
lots and lots of random I/O. This, and reliability is where SCSI kicks
SATA to the curb.
My plan is to slap these into a WinMe system, to be migrated to Linux after
I test out the performance. I will be using one drive and keeping the other
as a spare.
Given that I paid a buck for these drives, and with SATA becoming popular,
should I spend to get a controller card and cabling? Would trade one HD for
a card and cable.
Buying a decent controller and cables new will run you more than they
are worth (Based on the fact that you can get a new 80 GB drive for ~$50
(1) with no rebate and the cheapest SCSI card with a 68 pin connector is
~$50 (2) ).
Send them downstream or hold them till other pieces float by?!
If you really want to play with SCSI, I **might** have a Wide SCSI card
floating around... Not positive on that, but I might.
