Testing out a SCSI card.
This has all the info for the time being:
ST19171WC on Adaptec AHA-1542CP - Pastebin.com
Slow, I know. This is what I get for not using MCA! :P

Need to dig up some more drives to bench and also take some pix. :)

ummm.. you have a system with a ISA bus right?

Yes, the SCSI card is in a 16bit ISA slot in my 286 atm. The Seagate ST19171WC is connected with an 80-pin to 50-pin adapter. Unfortunately the two compaq BD0366459B drives I have are not usable with the same adapter. I would need a less-cheapcrap one.

On a side note, I actually no longer have a board with MCA slots but according to a guy I know with an MCA equipped 386SLC system & SCSI card, you can pull 3MB/s to 4MB/s from a 1997ish SCSI drive. Much faster! :P

That particular drive shouldn't have a big problem pushing 10-12mb/sec. And on random I/O, such drive is still very competitive with brand new 7200rpm current generation drives.

The -WC means that it is designed to plug into a SCA backplane that uses single-ended (not differential) 16-bit wide SCSI.
