SATA 3 vs. SATA 6

Hi I was just looking at my parts, and realized I have an SSD(Samsung Evo Drive), but my board only supports 6 gb/s. Isn't that SATA 3? And if it is, than how much will it suffer if I do use the SATA 3 vs. using a SATA 6?

    SATA 3 = SATA 6Gbps
    SATA 2 = SATA 3Gbps

    That EVO is fine on that motherboard.
  3. 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.

  4. 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.
