Well, they're a bunch of modifier obsessed weenies, anyway. I mean, geez, we have:

SCSI
SCSI-2
Wide SCSI
Fast SCSI
Fast/Wide SCSI
Ultra SCSI
Ultra Wide SCSI
SCSI-3
U160 SCSI
U320 SCSI

...each with a subtle variation in cabling requirements. Moreover, some of them come in 3 cabling variants: LVD, HVD, SE.

I don't think that any mere mortal can keep track of it.

What's next? Hyper SCSI Ultra Mega 640: Washes whiter than white! Kills all known germs! Decrypts WW2 German naval transmissions!

Except that we've probably already seen that announced already.
