I just bought a Corsair Force GT 120gb SSD to replace my first generation Sandforce drive. Corsair claims up to a 550 mb/s read. Reviews have also shown this to be true. However, I'm not getting close to this. I'm only hitting about 390. The motherboard has Sata III ports, so I'm not sure why I'm not getting a faster read. I've read conflicting information regarding cables. Some say that using Sata II cables makes no difference. Others argue that you need Sata III cables to max out speeds. I'm currently using Sata II cables. Does anyone know for sure if the cables can really make that much of a difference?
