Most often when carrying out any Linux file-system benchmarks -- or really, any benchmarks in general -- on Phoronix it's using solid-state storage. SSDs are just too great to pass up with their incredible performance. However, for those still using rotating media, here's a collection of file-system benchmarks from the new Linux 3.8 kernel when tested on a Serial ATA 3.0 Western Digital hard drive.
Though SSD does not possess any moving part then too SSD testing should be comprised of pre-qualify their SSDs by testing them using industry standard, qualification testing systems such as SNIA's Solid State Storage Performance Test. or Linux 3.8 File-System Testing.
