Hi,

I'm torn between two different yet similar hard drives:

Western Digital Caviar Black WD1501FASS 1.5TB 7200 RPM 64MB Cache SATA 3.0Gb/s 3.5" Internal Hard Drive -Bare Drive http://www.newegg.ca/Product/Product.aspx?Item=N82E16822136592

and

Western Digital Caviar Black WD1002FAEX 1TB 7200 RPM 64MB Cache SATA 6.0Gb/s 3.5" Internal Hard Drive -Bare Drive http://www.newegg.ca/Product/Product.aspx?Item=N82E16822136533&Tpk=wd1002faex

I was wondering which one I should choose, and why. Keep in mind that I definitely like the 1.5 TB model more, but will I need the 6.0Gb/s on the 1 TB model? I'll be using my PC for gaming. Here are my specs:

Get the 1.5TB drive.

Why?
Because these drives are not bottlenecked at the transfer speed they are bottlenecked by the fact that they are spinning mechanical drives. The new SATA III (6.0 Gb/s) is only really utilized by solid state disks. A lot of people think there will be a big increase in speed using the new interface but the old interface is fine for all but the fastest disks which would only see a small speed increase. Solid state drives are capable of very fast transfer speeds and can actually max out the ability of SATA II.
