NAS Testing Results
With so many features available to offer a broad range of functionality, NAS server products can be daunting when you try to nail down performance. In this article, Benchmark Reviews will refer to performance as the bandwidth speed results of a file transfer test. The first tests we perform utilizes a single 1GB (1000 megabytes / 1,000,000,000 bytes) file in a transfer to and from the NAS. This test used to take as long as a minute back in 2007, but in the past few years there have been major gains in NAS transfer performance. Now our 1GB Read test ends in as little as seventeen seconds (with the QNAP TS-509 Pro). Using an FTP tool so that exact transfer time could be captured, each NAS was tested for transfer bandwidth.
As you can see for yourself in the chart below, QNAP has certainly set itself apart as the dominate force in file transfer speed. The TS-509 Pro doesn't offer Jumbo Frame support so all of our tests use the same result twice; but even without the extra packet size we see that QNAP has designed for optimal transfer performance. At 58.8 MB/s read bandwidth the QNAP TS-509 Pro is our highest 1GB performer, with the QNAP TS-119 and Synology DS408 coming in close behind with a best of 55.6 MB/s each with Jumbo Frame. The Thecus N7700 comes in right behind the top three leaders, with a best of 50.0 MB/s, matching performance with the Synology DS209.
Moving on to the 1 GB write bandwidth test, our results suggest that sometimes it will be faster to read files from a NAS server then it is to write files onto it, and sometimes the opposite is true. The Network Attached Storage servers each have their own strengths, with some being more robust in write-to performance when others conformed to the traditionally impressive read-from performance.
QNAP's TS-509 Pro maintained 62.5 MB/s without the comfort of Jumbo Frame support, followed by the Thecus N7700 which produced a best of 62.5 MB/s. The Synology Disk Station DS209 narrowly beat the larger DS408, and scored a swift 43.5 MB/s write performance with Jumbo Frame enabled. A single-drive QNAP TS-119 held a steady 33.3 MB/s speed, scoring the same with and without Jumbo Frame enabled, and was tailed by the Thecus N3300 at 32.3 MB/s.
The lower-end spectrum consists of all the remaining NAS products, with the next closest competitor being the QNAP TS-409 Pro which reached only 20.3 MB/s write performance using Jumbo Frame, and 16.5 MB/s without it. The older Synology CD407 performed at roughly half the speed of its newer predecessor, and the remainder of the bunch trailed distantly behind. Let's move on to the larger file chunk testing, because next up is our 10 GB (1000 metric megabytes / 10,000,000,000 bytes) tests. Using only a single hard drive for testing in each NAS, network throughput would be put to the test.
Fresh out of the gates, QNAP's TS-509 continued to impress us with the high-bandwidth read performance of 55.6 MB/s that lead the pack. QNAP's single-drive TS-119 offered the same performance once Jumbo Frame was enabled, but reduced to 47.6 MB/s at 1500 MTU. The Synology DS209 and DS408 maintained a close relationship with peak performance around 47 MB/s in normal mode, and improved to 49.3 and 48.3 MB/s read performance with Jumbo Frame enabled at both ends (respectively). The Thecus N7700 was able to sustain 44.5 MB/s using Jumbo Frame, and 41.5 MB/s without it, which was very similar to the N3200 Pro.
In our 10GB write performance tests, the charts were shuffled a bit. The Thecus N7700 makes up for above-average read performance by offering excellent large-file write performance and sustained 56.2/58.8 MB/s in normal and Jumbo Frame modes. Next was the TS-509 Pro, which has held the top position for most tests, and scored 47.0 MB/s. The Synology DS209 and DS408 have performed in the middle of the pack for our 10GB file transfer tests, and performed at 42.9/40.0 and 36.8/36.3 MB/s in normal and Jumbo Frame modes.
The single-drive QNAP TS-119 and three-drive Thecus N3300PRO both score around 32 MB/s in our large file JBOD tests, and trail behind the leaders by almost 20 MB/s. Taking the entire test section as a whole, one thing becomes abundantly clear: QNAP keeps the bar high for NAS performance with their Turbo Station TS-509 Pro, even when compared against newer products.
