It would be better if instead of (or in addition to) PCMV, tweaktown ran ASU with 100% incompressible data, or AS-SSD, on the drives when they are 25%, 50%, and 75% full, etc.

It would be interesting to see how AS-SSD and ASU benchmarks vary as the SSDs are filled up.
The problem with those tests are they show peak performance and not average performance. Peak numbers don't tell you anything other than the best possible outcome. The next PC Mark will be a lot different and will aid in what I'm doing. Then there is the my own trace based tests, as soon as I can convince Bus Trace to send me the software I'll start thinking about building my own PC Mark HDD tests and call it ChrisMark
