I'm looking to get another hard drive for my computer. How can I figure out which type my PC uses? SATA, SATA II, and I think there's another type? Or are they pretty MUCH universal? An internal drive is what I'm looking for, by the way. If it helps at all, here's my specs:

Intel Core2 Duo E6750
ASUS P5N-e SLI mobo (I don't use the SLI feature though)
GeForce 9600 GT
2GB system ramHere are the specs for your motherboard...

It would seem...your computer's motherboard will accept SATA drives.copyjust an ADDED note, some SATA harddrives come with jumpers to change the transfer rate from 1.5Gb/s (older SATA motherboards transfer speed) to 3.0Gb/s (newer SATA motherboards transfer speed). since your motherboard is able to support SATA devices @ 3.0Gb/s, you are GOING to have to check that your harddrive is set to run @ 3.0Gb/s.

P.S. just ignore the whole SATA/SATA2 thing.Okay, so basically as long as I have the proper cables I should be able to use either IDE or SATA?

Thanks for the quick REPLIES, I appreciate it!Correct.
Your MBoard will support up to 4 IDE drives ( HDD or Optical ) and up to 5 SATA drives...

I just finished a build with the P5N board which is similar but only has 1 IDE channel so it limits me to 2 IDE drives without an add-on card.

Good Luck.
