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.
The TS-453B didn't crack the 100MB/s mark for either reads or writes in our backup/restore tests although it got mighty close when it came to reads in all arrays bar RAID 5.
