7200 ATA66 or 5400 ATA100

[Stoanhart]

I just got some leftover hardware from school, which included a 20gig, ATA100 5400RPM HD. My brother's machine only has a 20gig 7200RPM, but it's ATA66 which sucks (anyone who has run a high performance machine on a ata66 then switched to ata100 will know). I told him I would give him the better one, and use the crappier one on my spare computer.

What's better: 5400RPM ATA100 or 7200RPM ATA66?

the 7200 will be better.

IMO: Not to be argumentive but, why would you pick an ATA66 over an ATA100 drive? My understanding is that ATA100 will be able to transfer up to 100mbs per second while ATA66 will only do 66Mbs, actual rpm's can be misleading without knowing what brand of drive it is. The number of platters in the drive seems to account for actual information transfer speed as much or more than the rpm's.
