Everest Ultimate and Corporate Edition offer several different benchmarks for testing and optimizing your system or network. The Random Access test is one of very few if not only that will measure hard drives random access times in hundredths of millisECOnds as oppose to tens of millisECOnds.


Read Tests




Despite both the XT and Caviar Black using 7,200 RPM platter speeds, the Caviar Black has a lower access time. Running drives on the Marvel SATA 6G controller didn't increase latency by any measurable amount, but running a pair of drives in RAID 0 did increase latency.


Write Tests




The single drive write latencies were nearly identical across motherboards. The U3S6 on the unapproved P6T7 had a wild run down the benchmark graph with several spikes .Once again the Western Digital Caviar Black is lower on both motherboards. The RAID 0 numbers went down this time due to having twice the cache available.


Let's see how all of these synthetic benchmarks relate to real world applications.
