IOMeter is another open-source synthetic benchmarking tool which is able to simulate the various loads placed on a 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.
Synology’s DiskStation DS120j had no problems dealing with our backup/restore tests. The extra memory installed in the new model shows its advantage when it comes to the write performance when compared to the previous DS119J.
