    i'm about to order a mbp and was wondering about the base hdd, will it make use of the new SATA III port speed? and the optical drive, is it SATA III as well?

    My 2011 13" base MBP shows that both bays are SATA III.

    To add, the SATA III speeds are faster than a HDD can read/write, so only a SSD would be able to make full use out of the SATA III speeds.

    The HDD may be, but its not fast enough to make a difference. The optical drive probably only has a sata 1 interface, however, again it wouldn't really matter.

    ^This. The average stock hard drive puts out around 60MB/s, which is well below the SATAII threshold. You should have 2 SATAIII ports though.

    Not sure what you are asking. The 13 and 15 models have SATA III speed in the Hard drive bay...only some have SATA III in the disk drive (not
    sure which production period).

    The base HDD will not feel any faster because the hard disk speed is based on size, density, and RPM.

    But if you are asking whether you could use a SATA III/6 gbps drive in the base mbp 13, then the answer is yes.

    Hope this helps!

    You can do any combination of ssd/hdd. No problem!

    Main drive/SSD in the hard drive bay @ SATA 6Gbps speed and secondary hdd in the optical bay at SATA 3Gbps speed.

    Now SATA 6Gbps has issues in the optical bay AND in 17" MBPs

    Vendor: Intel
    Product: 6 Series Chipset
    Link Speed: 6 Gigabit
    Negotiated Link Speed: 6 Gigabit

    Secondary drive-hdd (ie, optical drive):
    Vendor: Intel
    Product: 6 Series Chipset
    Link Speed: 6 Gigabit
    Negotiated Link Speed: 3 Gigabit

    The base HDD will not take advantage of SATA III. Most can't even max out SATA I which is 1.5 gb/s.
