Performance - Summaries

4.0.1 firmware was loaded on the TS-420 for our standard NAS test process. As noted earlier, all testing was done on the TS-420 sample. The TS-420 tests used four drives configured in single RAID 0, 5 and 10 volumes. The TS-220 tests used two drives in single RAID 0 and 1 volumes. The TS-120 tests used one drive.

As I found with the TS-421, times to completely build and resync 4 x 3 TB RAID 5 and 10 volumes were quite long at 17h 20m and 23h 5m, respectively. Build and resync for 2 x 3 TB RAID 0 and 1 volumes were 32 minutes and two hours, respectively. Unlike Thecus and Synology, QNAP does not offer the option to skip a bad block test, which can speed volume resync times significantly.

Since we have the NAS Ranker, I'll only make a few observations about each benchmark summary. The TS-420's below shows best file copy throughput with RAID 0 (53 MB/s) and worst with RAID 5 (34 MB/s). Read is best again for RAID 0 (79 MB/s) with both RAID 5 and 10 read about 10 MB/s lower. NASPT file copy write performance is lower across the board for write and about the same for read.

QNAP TS-420 Benchmark Summary

I was not able to run the Network backup (rsync) tests on the TS-420 because QNAP has not fixed the bug that prevents selecting a remote target directory yet.

With two drives representing the TS-220's performance, RAID 0 performance is in the same ballpark as with four drives. Windows file copy for RAID 1 measured 42 MB/s for write and 66 MB/s for read. NASPT file copy was a tad lower (40 MB/s) for write and almost 15 MB/s higher for read.

QNAP TS-220 Benchmark Summary

With only a single drive, both write and read performance dipped to 46 and 70 MB/s for Windows file copy and 33 MB/s and 65 MB/s for NASPT file copy.
