I took a look at that centrix site... I could use a little help with the
basics:

1. I have an Adaptec 2940UW, which transfers at 40/80mb and so is not
capable of 160mb transfers, but it has both 50-pin and 68-pin internal
connectors. I am only using the 50-pin internal connector. I am assuming
that I can use the 68-pin plug to add a second string of drives if I wish...
correct?

What is the compatibility, ie, I assume a newer/faster adapter would handle
older 40/80mb transfer rate drives, but do I need a newer adapter to handle
the 160mb transfer 10K rpm drives, or will they synchronize their transfer
speed to match the older 2940UW adapter?

2. The same vendor offers 9gb 10k rpm Western Digital drives for $35, less
than the IBM equivalent at $59... what makes the IBM scsi drive worth the
differential?

3. Are the drives offered by centrix used, or new?

Anything else I should be aware of in the mixing and matching of scsi drives
and adapters?

Thanks,

Wayne
