A bit of a silly question, actually rather of a call for confirmation.

I'm building a new PC with a mobo that supports SATA 6 Gb/s, and getting a HDD to match. Now, I have a 3 Gb/s drive from my other PC I was hoping to stick in there along with it.

Am I correct in assuming that as long as the SATA 3 Gb/s is plugged in, the 6 Gb/s will always run at the lower speed? The second question is: would it really make a huge difference?

thanks!

doesn't your mobo have 3gbps ports? :/

yes, SATA II and SATA III are forwards and backwards compatible

but a SATA II drive plugged into a SATA III port will run at SATA II speeds

^ But you have to jumper select the SATA3 to function as sata2, which isn't well supported by mobo's, its supported, but not well.
