    All you need to know:

    · Point 1: port's max speeds:

    ----------------------------------
    Sata 2 max speed = 300mb/s
    Sata 3 max speed = 600mb/s
    ----------------------------------


    · Point 2: HDD/SSD's max speeds (on best manufactured models), depending on the sata connection:

    ................................. Sata 2 ............ Sata 3

    HDD 5400rpm ......... 80mb/s ........... 80mb/s
    HDD 7200rpm ......... 100mb/s ......... 100mb/s

    Sata 2 SSD .............. 285mb/s ......... 285mb/s
    Sata 3 SSD .............. 285mb/s* ....... 550mb/s


    * Note: Sata 2 only affect's you if you want to put a sata 3 SSD in the optical drive's port, of an early 2011 macbook pro that doesn't have a sata3 port in that bay, because it will go at 285mb/s, in the rest of cases JUST DON'T WORRY.


    · Point 3: macbook pro's sata configurations:

    ................................................. HDD Bay's port ........ Optical Bay's port

    Early 2011 ....................................... Sata 3* ...................... Sata 2*
    Summer 2011 .................................. Sata 3 ........................ Sata 2/3*
    Late 2011 (6770 GPUs gen.) ............. Sata 3 ........................ Sata 3*
    Mid 2012 - Early 2013 ...................... Sata 3 ........................ Sata 3

    *Note: some 17" models had problems with sata 3 speed in the main drive because the cable had interferences. OWC sarted selling a sealed cable.)

    *Note: Early Sandy Bridge chips where all faulty. They had a design flaw that made all Sata 3 ports but one useless and it can't be fixed by software. Intel warrantied that those manufacturers that decided to mount their chips wouldn't have any problem if they used only one sata 3 port, and the others in sata 2. Apple didn't needed even one, because the SSDs they were selling were sata 2 models that didn't even reached 300mb/s, so they decided to start selling sandy bridge macbook pros with that faulty proccessors.

    *Note: Intel relesed Sandy bridge revised version with all sata 3 ports enabled.
    Apple started adopting them and selling them mixed with faulty ones.

    *Note: Revised Sandy Bridge chips fully updated


    · Point 4: check your optical's drive sata version in OSx's Sys Info


    If something is wrong just post it an I will change it.

    This issue was solved with a firmware update and OWC thus discontinued sale of this "sealed" cable.
