Really considering the Vertex 4s/Agility 4s as they are dirt cheap right now. I had a few Sanforce just disappear on me, so that left a bad taste for anything Sandforce no matter how cheap. Going with everything else right now. Since its basically Marvell based, it seems like the one to go for bargain basement prices. I upgraded from Intel G2 to Samsung 830 and there is def a difference. Esp in image editing. Something processes and thumbnail creates were almost twice as fast. Did a lot of testing and was very consistant. Even made a huge RAMdisk to test out and RAMdisk was only 10% faster in most! We are pretty maxed out in SSD performance it seems, esp with Sata III. We really need SATA 4 to come out soon!
