1GB Single-Disk Test 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. On products that support the feature, tests using the EXT3 and EXT4 file format will be included. 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... even without the aid of Jumbo Frame support on their NAS products. The TS-809 Pro is built from similar hardware found in the TS-509 Pro, and even without the extra Jumbo packet size we see that QNAP products are designed for optimal transfer performance. At 62.5 MB/s read speed (using EXT4) the TS-809 Pro competes on the same level as the QNAP TS-459 Pro. With 55.6 MB/s read speeds at 1500 MTU and 66.7 MB/s at 9000 MTU, the QNAP TS-459 Pro could very well be the top contender here.
Next in line is the TS-509 Pro with 58.8 MB/s using EXT3, matching the 58.8 MB/s read bandwidth of the QNAP TS-509 Pro. The single-drive 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. Although the QNAP TS-419P shares the same hardware as the TS-119, for some reason it didn't post the same performance numbers and dropped back to 50.0 MB/s with Jumbo Frame support.
Moving on to the 1 GB write bandwidth test, our results suggest that while it may sometimes it will be faster to read files from a NAS server then it is to write files onto it, the opposite is true more often than not. 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.
At the top of our charts the QNAP TS-809 Pro offers the highest performance with EXT4, as it did in 1GB read tests, and yields 76.9 MB/s. Formatted with EXT3, the TS-809 Pro offered 71.4 MB/s, followed by the QNAP TS-509 Pro which maintained 62.5 MB/s without the comfort of Jumbo Frame support. Next came the Thecus N7700 which produced a best of 62.5 MB/s, which finishes out the list of top-performers.
The QNAP TS-459 Pro NAS server produced 41.7 MB/s at 1500 MTU, and remained relatively unchanged with 41.8 MB/s once 9000K Jumbo Frame was enabled at each end. 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-419P which scored a noteworthy 25.6 MB/s. The QNAP TS-409 Pro 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.
10GB Single-Disk Test Results
Examining 10GB basic file transfer speeds, QNAP's TS-459 Pro, TS-809 Pro, and TS-509 Pro continued to impress us with the high-bandwidth read performance. At 56.2 MB/s standard and 65.4 MB/s with Jumbo Frame enabled, the QNAP TS-459 Pro delivers phenomenal performance. The QNAP TS-809 Pro and TS-509 Pro both provide 55.6 MB/s without the use of Jumbo Frame. 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). At 50.3 MB/s with Jumbo Frame support, the QNAP TS-419P offers very good large file transfer speeds, but without JF support the speed slows to 39.8 MB/s. 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, and for once QNAP was not the performance leader. Next in line came the QNAP TS-809 Pro with 54.4 MB/s using EXT3 and 48.3 MB/s with EXT4. Then came the TS-509 Pro, which has held a top position for most tests until now, and scored 47.0 MB/s. QNAP's TS-459 Pro dropped to 39.2 MB/s at 1500 MTU and 40 MB/s with Jumbo Frame enabled. 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. QNAP's TS-419P illustrates a weakness in write-to performance, and produces only 25.4 MB/s at its best and trailing it's CPU/RAM clone (TS-119) by 7 MB/s. In each and every test the Patriot Corza NAS performed poorly compared to similar network storage appliances, but then again this network appliance costs less than $100.
In our next section, Benchmark Reviews tests these network storage appliances with RAID-5 disk configuration.
