    My hdd had few errors and I decided to buy ssd, finally.
    So I want to put ssd in place of hdd - and do fresh install.

    After a week when optibay will arrive to me I want to add hdd.

    what is better, hdd in normal place and ssd in place of superdrive?
    Or ssd in place of hdd and hdd in place of superdrive?

    If you have a 2010 or 2009 or 2011 MBP, HDD in HDD bay, SSD in Optibay. If you have a 2011 or 2012 MBP with S-ATA 6.0 Gbps (S-ATA III) and S-ATA 6.0 Gbps (S-ATA III) is not available in the Optibay, then SSD in HDD bay and HDD in Optibay, if your 2011 or 2012 MBP has S-ATA 6.0 Gbps (S-ATA III) available in the Optibay, put the SSD in there.

    The HDD is almost always better off in the HDD bay due to the Sudden Motion Sensor.

    I'm glad I saw this as I'm about to get a SSD to add to my 2011.

    How do I determine which is better? Does it just depend on which model?

    thanks for quick answer!
    Just to confirm:

    hdd sata: http://dl.dropbox.com/u/822537/Screenshots/macbook_sata_hdd.png
    Link speed: 6 Gigabit
    Negotiated Link Speed: 3 Gigabit

    dvd sata:
    Link Speed: 3 Gigabit
    Negotiated Link Speed: 1.5 Gigabit

    So, ssd in hdd bay, and hdd in optibay, right?

    And my second, last question:
    I would like to install ssd in hdd bay, install system etc.
    Then in next few days I'll buy optibay and put there hdd - it will not make macosx confused about from which device he should boot the system? Or cause any other issues?

    I'm not sure that I understand how an electronic accelerometer relates to the location of a drive bay, but from the pure mechanical perspective, the HDD will be suspended by rubber bushings in the HDD bay. Whereas SSD which doesn't (or shouldn't) care about mechanical vibrations, can safely be hard-mounted in the Optibay.
    Perhaps there are other HDD adaptors available, but the one I had, was totally rigid.

    The Sudden Motion Sensor works via software means, maybe the three links I posted again can shed some light on this and why the SMS only works in the HDD bay and not the Optibay and why it is irrelevant if the HDD has rubber or nitro-glycerol feet.
