They totally missed "mainly write" applications which most of my applications are.
Not totally--the very first graph shows that even on random data, 100% write apps are 1/2 the speed of a regular hard drive.
After poking around the site a bit more they also did some tests with MFT, some kernel software from Easy Computing that basically uses a write log disk to improve the write situation:
