Sata3 HDD compatible with Sata2 port?

post #1 of 4
Thread Starter 
I'm asking because the motherboard I'm getting (M4A79XTD-EVO) only supports Sata 2 (3gb/s), not Sata 3 (6gb/s).

However, for the same HDD (WDC Black 500GB), I can get the Sata 3 version (WD5002AALX) for $10 cheaper than the Sata 2 version (WD5001AALS).

So just wondering if I can plug a Sata3 HDD into a Sata2 port and it will still run at 3gb/s?

Thanks.
