Mixing SATA 3 Gb/s and SATA 6 Gb/s Tags: Hard Drives SATA Storage Last response: August 24, 2010 9:38 PM in Storage Share Anonymous a b G Storage August 24, 2010 8:41:53 PM 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!
