[citation][nom]climber[/nom]SATA 3.0 is 6Gb/s, SATA 2.0 is 3Gb/s, salimbest83 was more than likely referring to SATA 3.0. That being said, this drive can't beat the current SATA 2.0 read/write speeds of the interface so don't worry.[/citation]
AMCC doesn't refer to the different SATA generations as 1.0 2.0 or 3.0, they label according there interface speed so what you call SATA 2.0 is actual SATA 3 as is 3 Gb's and what you call SATA 3.0 is actualy SATA 6 as it's 6Gb's.
That's a good idea as it avoids confusion so when SATA 6 is more common place it's clear as to what generation is being discussed otherwise if you say SATA 3 someone might think your talking about SATA 3Gb's i.e the second generation rather then SATA 6Gb's.
