I'm new to the realm of SCSI, so I've got a few questions. Would a Ultra160M/LVD/SE drive work with an Adaptec 2940UW or would I need a 2940U2W? That the only thing I can't figure out ATM. I know both cards have the 68 pin connector, but not sure which I'd need. Thanks all.

If it has a 68-pin connection it'll work just fine. The only difference you'd see between using an U2 SCSI card and an U160 SCSI card is that if you were using multiple drives you'd quickly get to the saturation point of your bandwidth.

U2 = 80MB/sec
U160 = 160MB/sec

Using a single SCSI drive you're not going to get close to either one of those numbers. In fact, most drives will operate at a sustained rate of less than 30MB/sec.

Cool, thanks. Time to get a 2940UW. SCSI here I come.

One more thing I forgot to add, the drive is Wide Ultra SCSI. Would that make it able to run on a 2940UW instead of a 2940U2W?

<< yes the uw on 2940uw stands for ultra wide. >>



Nice. Thanks for the help guys.
