Some SSDs are simply slow. Remember when Apple first introduced SSDs and while it reduced heat/noise and make it more shockproof, they were actually slower than HDs. I'm going to guess that the second HD being tested is a OCZ Vertex LE, which is one that I have. It's a ridiculously fast SSD, however it has a lot of variance based upon the compressibility of data (as the Sandforce controller's advantage largely comes from dynamic streaming compression).
