HDD Questions

[ffaucg]

I'm looking for a SATA HDD and would like to know where I can find info about which sized disks and how many platters they have. So far I've narrowed down my choices to three sizes.

Either 500, 640, or the 750 GB Drives

I would like to know if the Hard Drive cache matters and if I should get a HDD with a 32 MB Cache. Also my friend told me that disks with less platters work better because of the areal density or something?

Last thing is I would like the drives not to be too noisy, it doesn't have to be dead silent.

WD GP drives are quiet, and very nice in general, but they do sacrifice a little bit of speed.

500GB or 750 GB drives probably have 250 Gb platers

640 is still a toss up.

WD6400AAKS should have a few more specific numbers behind it to identify platter size.

(i think we had a topic about that here already)

Yea I know about the GP, but I'm not gonna sacrifice performance for that, Im only looking for the 7200 rpm drives.
