What's the speed difference between a SATA 3Gb/S connection and 6gb/s Tags: SATA Connection Storage Last response: December 8, 2012 6:49 PM in Storage Share darksparten December 8, 2012 6:10:48 PM I plan to put my Caviar Black 7200RPM/64mb Cache on my SATA 3/Gbs and my two SSDs on my only 2 SATA/6GB/s connections, because my BOXDX79SI only has 2x SATA 6GBS and 4x SATA 3GB/S what will be the difference in performance with the HDD on the 3gb vs the 6gb, will the difference be noticable. Thanks.
