    Hi all.

    I had the idea for some time and I am about to try it .

    I recently bought and exchange on my Late 2010 13' Air the 128 with an 256.

    The Idea is to buy one 6 + 12 Pins SSD adapter card to 2,5 SATA and THEN put it to a SATA caddy and exchange the DVD/RW of the late 2009 (11.1) 27' iMAC .

    The good think is that i will not worry about Trim support on Yosemite PLUS the ssd is natively Sata II so i guess it will match perfectly to the SATA chipset of the iMAC.

    My worries are focused on the size of the adapter card :(

    I was thinking about the below parts:


    What do you think?

    Will it work or do you have any other adapter/solution ?

    Links don't work. But why are you trying to put a MBA SSD in there?

    Enabling trim isn't difficult (nor dangerous), and there's plenty of room for a regular SSD.

    Thank you for your reply Brian.

    Links are fixed.

    I know that Trim can be enabled for 3rd party SSDs on Yosemite but I dont want to waste the MBA SSD in to a usb adapter case nor spent 150$ for another SSD.

    The idea is to give to the good old iMac a fusion drive so i will have the 1TB of space AND the performace boost of the SSD.

    Also by using the MBA SSD i will bypass the issue of the low performance on SATA controller
    (As per OWC

    "Special note for specific 2009 iMacs.
    We highly recommend the use of a SATA 2.0 (3Gb/s) SSD such as the OWC Mercury Electra 3G for the following iMacs:
    iMac models with model ID:
    How to find the model ID
    While a 6G SSD does function, it will only do so at SATA Revision 1.0 (1.5Gb/s, 150MB/s) speeds rather that the SATA Revision 2.0 (3.0Gb/s 300MB/s) speed the computer can deliver.
    The Mercury Electra 3G SSD is the OWC recommended upgrade option for the iMacs listed in the special note above."

    What are my chances to make it work ?
