IOMeter is another open source synthetic benchmarking tool which is able to simulate the various loads placed on hard drive and solid state drive technology.
We set IOmeter up (as shown above) to test both backup and restore performance on a 100GB partition.
As in the NASPT benchmark, in our backup/restore test the slowest performance came from when the drives where built into a RAID 6 array with the best performance coming from the RAID 10 array.
