Or should I ask which is faster? Here are the two candidates: ST31000528AS or WDC WD6400AAKS-22A7B0. I ran diskbench on both of them, and the 640gb western digital was slightly faster. I don't know how accurate that software is, but the cache on the seagate 1tb is double that of the WD 640gb(32mb compared to 16mb respectively) I really don't understand how these HDD specs work. Are larger capacity drives a little slower maybe? I'm also waiting on a 2tb 5400 rpm drive in the mail, which I obviously won't be using for OS. I just want my os on whicever is faster until I can grab a ssd.

If it helps I'll be dual booting Windows 7 and Ubuntu. Thank you!


whoops this would help ay?

I had a feeling that was the case. I just wasn't sure because the 640gb is a couple years old, and the 1tb is a few months old. You'd think they would be able to make a significant difference in mainstream hdd speeds in that time period ay? Well, since the 640gb has lasted this long I guess I'll choose that one for the new build since it has proven it's reliability (still don't trust these 1gb+ drives).

I'm also upgrading from my os being on an old, old 250gb drive which is way too slow, so i'll see a good difference I believe. Thanks for the reply, can't wait for this gaming/media pc to be put together, hooked to 55 inch lcd. bring on the bad weather...
