    Hi everybody
    I have an iMac 20" early 2009 2.66GHz for which I'd like to replace the old internal disk with an SSD unit.
    Only, I have had controversial responses from various assistance services; while some say SSD are perfectly supported by the machine, others denied this possibility.
    Anybody who has already gone through this or could tell me what the reality is on this issue??
    Thanks to all for the help

    All you need is the correct SSD. If your Mac is using SATA II HDD, then any SATA III SSD (e.g. 850 Evo) will work, but speed cap at SATA II speed (which is not an issue at all, the main benefit to use SSD is high IOPS but not high sequential speed).

    However, the new PCIe / NVMe SSD won't work in your Mac.

    If you dont want to take the risk of physically replaceing the old HD, you could always boot from an external SSD once the OS has been copied to it with "superduper". I did this yesterday via USB but will be faster when I get a firewire connecting dock (which is on its way).

    I have one in an early 2006 MBP, and it works fine. Heck, people have added SSD's to iPods. Your iMac will run one just fine and it will be MUCH faster than a HDD.

    Make sure you get a FireWire 800 enclosure with external power.

    I tried doing this on bus power and while it seemed to work, every so often I'd get the spinning beachball of death. I then plugged in a power adapter, and it all worked fine.

    The main issue after that was lack of TRIM support and a drive that is mostly full. With a drive that is nearly full, speed would slow down to a crawl at times.

    It has to be. I have an SSD installed in a 2007 iMac.

    Samsung Evo definitely can be used on SATA II ports. I did it for few years already.

    And the performance as a OS / boot drive is virtually the same as connected via SATA III port. Again, I tested it by myself. My Mac Pro has both SATA II and SATA III port (via PCIe card). Both ports work with the Evo flawlessly, and both ports provide roughly the same boot time, same apps loading time, same system responsiveness. The only difference is when copying large files, or (un)zipping large files, etc, SATA III connection will be faster. That's it.

    iMac 20" Early 2009 Hard Drive Replacement/SSD Upgrade
    https://www.ifixit.com/Guide/iMac+Intel+20-Inch+EMC+2266+Hard+Drive+Replacement/919

    Most SSD's are 2.5" Form Factor you will need to purchase an adapter cage as the default Form Factor on the Early 2009 20" iMac is 3.5"

    Alternatively you could replace the Superdrive with SSD allowing you to retain the existing Hard Drive

    iMac 20" Early 2009 Dual Hard Drive
    https://www.ifixit.com/Guide/Installing+iMac+Intel+20-Inch+EMC+2266+Dual+Drive/8954

    If you can live without the Superdrive then I recommend the Dual Hard Drive option. Having the storage on the Main Drive you could use a 64GB SSD for running macOS and any software then read/write the files from the Main Drive.

    Alternatively you could go with a Seagate SSHD Solid State Hybrid Drive which offers performance and capacity up to 2TB which are available in 3.5" Form Factor and wouldn't mean losing your Superdrive
