That would be my conclusion.

In terms of what is the fastest consumer SSD I would say the C300 is technically the fastest (on either SATA 2 or 3) and I would put the X25-M & Vertex 2 at joint second based on an all-round performance assessment. You could find loads of benchmarks that might agree or disagree with that and I wouldn’t bother auguring with anyone on that basis and in the context that it doesn’t really matter anyway to most end users.

I’m also yet to be convinced that SATA3.0 will bring any real benefit for desktop users. When hardware and software becomes more SSD user friendly things will change, but when that will happen I don’t know.
