SCSI Disk limitations like IDE?

[covertclocker]

This is probably a dumb question, but I have an Adaptec 2940UW 32bit PCI SCSI card, and I would like to hook up some hard drives to it, however I don't know if the early size limitations like IDE of yore exist in SCSI land. Would I be able to hook up a 74GB SCSI drive if I wanted to? Thanks.

Scsi devices have, according to Wikipedia, 32-bit LBA addressing. This means you can address 2**41 bytes of disk, since a typical LBA size is 2**9 bytes (512). So that's way more than 74 GB. Shouldn't be a problem.

However, a 2940UW is only 40 MB/s. That's gonna be slower than a modern IDE disk in 99.5% of the situations I can think of. I'd look into getting a 160 MB/s card; they're technically outdated, but 160 is still more than the pci bus you're likely to be using it on, so it's not a problem. And they're pretty cheap on eBay last I checked.
