Ok well my thread description isn't completely accurate. I'm looking for an HDD for my current PC which doesn't have Sata6GB. PC spec is in my sig. I was thinking about buying a Western Digital Caviar Black WD1002FAEX 1TB 7200rpm SATA6GB/s so when the new CPU's from AMD and Intel hit the market next year i will probably want to upgrade my Mobo, CPU and Ram and hence will take advantage of the SATA6GB/s then.
I know SATA6GB/s is backwards compatible with SATA3GB/s, just want to know how will it perform against normal 7200rpm SATA3GB/s HDD's on a SATA3GB/s mobo? Will it perform exactly the same as SATA3GB/s drives or slower? faster?
