Partly true, partly not. First, I have never seen a 5200 RPM drive, but
I have seen 5400 RPM, 7200 RPM, and 10000 RPM drives. It isn't like
buying a car and not having the steering wheel, it is like buying a
porshe and never going faster than 100 MPH. It sure does get the job
done, but you never actually reach its max speed.
An ATA100 drive would not necessarily have been that much less expensive
as ATA133 is now the standard and are more mass produced than the older
ATA100 drives. This helps to aleviate the price differences.
Finally, I want a 16 MB Cache 10K RPM SATA drive

LOL
