SCSI drives were faster because higher RPM devices were available. 10 kRPM and 15 kRPM (!!!) SCSI drives were a thing, but I don't think there were many (any?) IDE drives that spun that fast.
WD's 10 kRPM drive made quite the splash when it was announced, IIRC:

Whether a home user "needed" that kind of speed was quite another thing.
- brudgers 5y agoMost businesses didn't need those fast drives either. Marginal disk speed increase did not contributing to the bottom line. I mean if you're going to disk, you've already lost money.
- bbarnett 5y agoThere was also more queue depth, allowing scsi drives to better order reads. And hot swapping was very trouesome with IDE (not to be mistaken for newer eide), where as scsi was much better at hot swapping early on. SCSI also had more bandwith than ide, and scsi2 was around before I could get eide/dma5?(80 conductor) cables/drives. Man, memories.
