Hey guys, I have an iMac 27'' from mid 2010 with a 2 TB harddrive. Bought it without SSD. Now I want to add a SSD, so I both have a SSD and the 2 TB harddrive. Which SSD do you recommend? My budget: 1000 Dollar. I want a very fast SSD with at least 128 GB. After installing the SSD I have to install the OS to the SSD, should I also format the harddrive or does it work without formating? Do you know any good tutorial for the iMac 2010 to add an additional SSD? Thank you.
