I currently have Sandforce 2200 series SSDs in all my 2011 Macs including a 240GB OCZ Vertex MAX IOPS boot drive in a 2011 Mac mini 2.7GHz Dual-Core Intel i7; and dual 240GB OCZ Vertex 3 MAX IOPS in a 2011 Mac mini server. In additional I also have a 480GB OWC Mercury Extreme Pro 6G in a 2011 15" MacBook Pro 2.3GHz Quad-Core Intel i7. I have several Samsung 830 SSDs that I've been testing in external Thunderbolt enclosures, so I can replace the Sandforce 2200 series drives with equivalent size Samsung 830 drives (240GB > 256GB, and 480GB to 512GB). Right now I'm on the fence if the time and labor is work switching the drives. I'm not experiencing any issues, so the only benefit would be better incompressible writes.
