    Howdy Guys,

    Just lobbed Crucial 256GB M4 SSD in to my mid 2010 iMac, and put it all back together and forgot to do what iFixit says and put the EMI foam pad from the old HDD on to the new SSD.

    Is this required? I'd rather not open her up again to put something on that really isn't necessary.

    Any advice appreciated!

    No you'll be fine. I've been inside of a number of iMac's. That piece of foam is there to help give support to a traditional hard disk since the insides are sandwiched together (as I'm sure you now know), and its sort of just laying there, propped against the rear of the machine. Since the SSD is not spinning up / spinning down, it'll be fine without it in my opinion. Enjoy the speed boost!

    You *should* be fine without it, but I won't recommend it. EMI foam also exists to block electromagnetic radiation, which could (in theory) damage the drive over time. Whether or not you will notice any difference, I can't say for sure, but "better safe than sorry".
