Filesystem SATA NCQ

Benchmarking disk write cache on a SATA2 NCQ capable configuration. I added a few generic CPU tests as a reference for the system performance. The tests are going to try different file systems with or without write barrier and w/ or w/out disk write cache. The default CFQ scheduler is being used.

Compare your own system(s) to this result file with the Phoronix Test Suite by running the command: phoronix-test-suite benchmark 1105175-GR-FILESYSTE14
