What determines the speed of a HD?

I'm looking to get a new HD, but size isn't a huge concern..anything over 60gb should do. However I'm much more concerned with speed..so what should I be looking for in terms of stats? They all seem to be pretty much the same in terms of buffer, rpms, and transfer rates..
 
Speed of the spin.
Measured in RPM's, this tells you how fast the HD spins. The faster it goes, the faster it can read and write data.
Seek time, the amount of time it takes to find something on the harddrive. The faster the drive, the lower the seek time.
cache, how much the harddrive is able to keep in a cache. This will make it easier for the manufacture to make a efficient drive.

Then there are other things that they don't mention in the stats on the side of the box, usually. Platter density, firmware intellegence, etc etc. In some instances one drive may out perform another, but have identical stats.

Then there are non-performance issues like reliability and noise.
