    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.

    Incompressible data reads are not impacted by Sandforce compression. The incompressible writes are impacted by compression and therefore 100MB/s slower than the Samsung 830 (according to AnandTech graphs). I see the speed difference in writes using Blackmagic Disk Speed Test.

    I didn't specify read or writes. Yes black magic shows this limitation. However look at Anandtech's real world benching which is more like real life usage and those show sndforce winning. To use one benchmark as the determining factor is asinine. You need to look at various benchmarks to truly decide.

    Incompressible writes a fairly important from a time saving perspective because large writes are typically h.264 video files in the real world.

    FWIW, I originally studied reviews that led me to go with Sandforce 2200 series drives. In particular, the OCZ Vertex 3 MAX IOPS for the IO performance I need.

    I'm just seeking the forums advice to see if I missed anything. I guess paulrbeers opinion is I made the correct choice?
