The simulated system backup into a single container file (66% sequential writes) is not significantly faster on the TS-559 Pro. Once again, the differences are larger in the RAID 5 degraded mode and RAID 6 mode.
Restoring the backup produces very similar results.
The difference between the Office Productivity benchmark compared to the Photo Album benchmark is that the files not only have to be read, but written as well. Also, the file sizes vary between 12 bytes and 197 MB. This means that the differences in data transfer rates are very small in the RAID 6 mode. The difference is measurable in the other RAID modes, but so small that it is practically irrelevant.
