Performance - Summaries
4.1.1 Build 20141003 firmware was loaded on the TS-653 Pro sample (2 GB RAM version) for our standard NAS test process. Since all four models use the same processor, RAM and Ethernet components, all testing was done on the TS-653 Pro sample.
Results from tests using four drives configured in single RAID 0, 5 and 10 volumes were entered into the NAS charts for the TS-453 Pro, TS-653 Pro and TS-853 Pro listings. The TS-253 Pro tests used two drives in single RAID 0 and 1 volumes.
The 6 hr 45 min to completely build and resync 4 x 3 TB RAID 5 volume was significantly improved from the 17h 20m we measured with the TS-451. Unlike Thecus and Synology, QNAP does not offer the option to skip a bad block test, which can speed volume resync times significantly.
For reference, here is the Benchmark Summary for the four-bay and greater models...
