Great job on the steady-state portion of the review!
But there were two major problems, the first is by far the worst:
1) Terrible choice of comparison SSDs. All 4 competitors were nearly equivalent Sandforce SSDs! What were you thinking?
The competitors should have been: Intel 520, one other Sandforce SSD (Vertex3, HyperX, or KC100), Samsung 830, Crucial m4, and Intel 320.
2) Your "real world" tests are flawed, and not at all representative of real world usage. For example, look at the "HTPC disk capture" test. Video files are a perfect example of incompressible data. And yet your Sandforce SSDs report rates of 450MB/s, which is close to the easily-compressible sequential write rates you measured with IOMeter of 460MB/s, and nowhere near the incompressible sequential write rates of less than 300MB/s you measured with IOMeter. Clearly your "real world" test is writing UNrealistic highly compressible files instead of real video files.
