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 setup IOmeter (as shown above) to test both backup and restore performance on a 100GB partition.
The TS-877 had no problems dealing with our backup/restore tests. With a 1GbE connection the NAS averaged 103MB/s for reads and 100.31MB/s for writes. With a 10GbE connection the transfer speeds are much faster with the exception of the write performance in RAID 6 where the transfer rates drops to 119.27 MB/s.
