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.

Dbench
Dbench is a benchmark designed by the Samba project as a free alternative to netbench, but dbench contains only file-system calls for testing the disk performance. Learn more via the OpenBenchmarking.org test page.
