SCSI drive compatibility

[drew at drewtaylor.com (Drew Taylor)]

Hi all,

As a bit of a follow up to my last post, I've begun thinking about 
replacement SCSI drives. I have an AIC-7880 on the motherboard, and would 
like to use it to it's utmost. I see that most drives these days come w/ 
SCA interfaces. I've seen adapters for SCA to 50/68 pin, so I know the 
physical side is OK. Can I use these newer drives w/ the older chipset? I 
know I won't get the best possible performance but that is OK.

For instance, I saw the following at Global Micro:
QUANTUM ATLAS IV 36.4GB ULTRA-160 SCSI WIDE 68 PIN LVD $256.00
QUANTUM ATLAS IV 36.4GB ULTRA-160 SCSI SCA 80 PIN LVD  $178.00

What is the difference? Thanks for your advice. I'm a bit ignorant in the 
SCSI realm.

Drew
