    I have an IMAC mid-2011 21.5*inch and I want to replace my 500 GB HDD by a barracuda 2 TB and add a 500GB SSD placed on the super Drive.
    I have a few questions because I see on various forums all and nothing…

    concerning the thermal sensor on the HDD
    I am going to shunt the thermal sensor and control the fans with a software using the smart datas. do you think it’s the better solution or the kit sold by owc is better (cable with thermal sensor)?
    Have someone experimented freezes with smart ?

    for the SSD someone recommend me to buy from OWC a cable with thermal sensor for SSD… but I don’t find it… do you have an idea?

    I thing the OWC solution isn´t cheap but perfect und works also with SSD .

    The Problem (I thing iMac 27 is the same princip -:) )) the internal SATA Superdrive Chipset interface works only max with 3 Gigabit/s
    and the Harddrive Chipset Interface with 6 Gbit/s

    Best solution is using the Second Harddrive interface connector and find a Place for your SSD

    SSD <-----> Hardddrive Connector
    HDD <------> Superdrive Connector

    I ve only replaced my HDD See my Config:

    The thermal sensor is the better solution, as it works regardless of the operating system used. If you use software you need one for OSX and another for windows if you use bootcamp.

    For the SSD, the best place is to install it in the spare sata port behind the motherboard. You need a standard sata cable and a special power cable, which you can buy from owc or on ebay.

    You don't need to remove the optical drive.

    The above is the normal apple arrangement for this model.
