Hello all. I have a mid 2011 27in i5 iMac. I recently upgraded to the RAM to 12gb. I'm wanting to upgrade my stock 1tb hard drive to a 120gb SSD. I figure I can run my programs on the SSD and use a couple external 1tb hard drives for content storage. My question is: Will my programs be able to be transferred to the SSD? Like for instance the Apple OS? Even more important, my adobe Lightroom 3? Thanks guys!!
