SATA 3 vs. SATA 6

6 Gbps SATA is SATA 3 (Third-generation SATA). I think what you are calling SATA 3 is actually SATA 2 (Second-generation SATA), which runs at 3 Gbps.
As far as differences in performance, a standard mechanical hard drive wouldn't notice the difference, since it couldn't fully load a SATA 2 connection, much less a SATA 3 connection. A solid-state drive, on the other hand, would have a large drop in performance on a SATA 2 connection due to it being many times faster than a mechanical hard drive.

A note when it come to naming SATA. There are like 3 different ways people do them.
1) By Version Number they use Roman Numerals.
SATA I - 1.5 Gbps
SATA II - 3 Gbps
SATA III - 6 Gbps
2) Sometimes you may see things like
SATA 1 1.5 Gbps
SATA 2 First Version of Sata II - 2.5 Gbps
SATA 2.5 Second Version of Sata II -- 3 Gbps
SATA 3 6 Gbps
And then you will see
SATA 1.5 Gbps
SATA 3 Gbps
SATA 6 Gbps
Which is by the speed.
Its easy to get SATA Gen 3 which people may put at SATA 3 which they should really say SATA III and it mixed up with SATA Gen2 for the 3 Gbps they may say sata 3.
So Moral of the story...Pay attention to what comes AFTER the number. If it doesn't say Gbps then ITS THE VERSION Not the SPEED.
