I have an ASUS PVI486-SP3 (486 PCI motherboard), and have the
opportunity to buy an SC-200. What is the performance difference
between a card like this, and a higher-end card like an Adaptec 2940?
The price is about $100 vs. $3-400 CAN, but I don't want to buy a SCSI
card which will barely outperform an EIDE system, which is what I
have. Also, what are some decent cached SCSI cards? I have an old VLB
Promise IDE 4Mb cached controller, and I want to exceed the
performance of this piece before I buy.
Suggestions?
Is there a SCSI buyer's FAQ somewhere? How about SCSI-III? Is it worth
waiting for, and what will the differences be?
BTW, what exactly is the SC-200 anyway? SCSI-II? wide? fast?
