Hi, I just got a Crucial m4 256GB SSD, http://www.amazon.com/Crucial-256GB-2-5-Inch-Solid-CT256M4SSD2/dp/B004W2JL2A/ My iMac is 27-inch, Mid 2010. Im going to take out my Super Drive , so I can have space for both iMac Internal HDD and the SSD both. I want to use SSD for OS data and Internal HDD for my work data . Right now, everything is in my internal HDD only. So, do I simply copy those folders to the SSD, excluding the USERS folder : http://d.pr/i/2X2l Or is there any other good way to move the OS data to the SSD ? So, after the copy, simply delete those folders from the HDD ?
