Yes im aware but a couple notes (for the record, i'm not so hot for SATA, more of an oldschool SCSI fan):
- 16MB SATA drives cost a premium compared even within SATA drives, 16MB SCSI drives cost relatively the same ... the 32MB SCSIs are a different story
- You can controllers with memory on them (think of it like the way L2 is to the CPU)..... except there are controllers with 128MB on then (maybe more too)
- Of course for the average user who maybe uses their computer a couple of hours a day ... 2MB, 8MB, 16MB ... they wont be able to tell that the difference is huge or anything
