I have a 27" 2011 iMac that I will be installing an SSD into. My question is, which SSD should I go with? I read that I should go with one that has a Sandforce controller so I wouldn't have to deal with TRIM and wanted to go with the Intel 530 SSD. However, upon further research, the 530 might have had compatibility issues with Macs. Any thoughts? Also, what have others who installed their own SSD used?
