Nice job, and beautiful graphs!

There are two more data points I'd be interested in seeing: the compression your Sandforce drive achieves on your C: and D: not-compressed archive files.

I guess you can measure it by just observing the SMART values on the drive, then copy one file to the drive, then look at the SMART values again to find the compression (assuming that attribute for actual flash writes is accurate). Maybe you have to delete the file and re-copy it several times to get an accurate measurement?
