Now it’s time run a few tests with our TS-109Pro II and DS207+ (in single-disk mode). Both are top-end products in the home NAS category and both are worthy of this positioning with their functionality and specs. Therefore our requirements to their performance are going to be strict. Here is a list of the equipment we used for this test session:

  • QNAP TS-109Pro II
  • Synology DS207+
  • Category 5e Ethernet cable
  • Intel Centrino notebook
  • Workstation with a Gigabit Ethernet controller
  • Seagate Barracuda 7200.10 hard disk drive (250GB, SATA-2)
  • Transcend JF130 USB flash drive (2GB)
  • Panasonic BL-C1 web-camera
  • D-Link DIR-655 router (Gigabit Ethernet)
  • IOMeter
  • FlashFXP FTP-client

We’ve got devices without WLAN modules today, so we are only going to measure the speed of their Gigabit Ethernet ports. For every disk-related test we connected the tested NAS directly to the testbed, i.e. to the notebook. We first measure the speed of the integrated HDD using IOMeter. There are two patterns: 512 bytes to determine for maximum amount of disk operations per second and 64KB to see the maximum data-transfer rate. We exclude random and write operations in both cases to get the highest results possible.

TS-109Pro II:


The QNAP product is considerably slower than the DS207+ in this test with the exception of the flash drive. We don’t count in the suspiciously high result of the DS207+ when reading from the flash drive (we discussed that in our DS207+ review). The poor performance of the TS-109Pro II with the internal HDD is probably due to the use of an integrated SATA controller instead of a discrete one (like in the DS207+). The high performance of the USB port of the TS-109Pro II is only achieved by means of its firmware because Synology’s NAS uses the same USB controller.

The next test is about the integrated FTP server available in both NAS devices. FTP remains an important data-transfer protocol, so this test has high practical value. We measure the data-transfer speed not only for the integrated HDD but also for an external device, a USB flash drive. We upload and download files with FlashXFP and mark the average download speed reported by the program in the server connection log. We use the following content types: a 700MB DivX movie (L), a 200MB folder with MP3 files (M), and a 200MB folder with photographs (S).

This test depends on the performance of the NAS’s processor, and the TS-109Pro II is now almost as fast as the DS207+. The latter is somewhat better, probably due to more optimized firmware.

Finally we wanted to compare images recorded from the web-camera’s interface and through the Surveillance Station. But although our camera is on the list of devices supported by the TS-109Pro II, we could only see a blank screen on the Live View tab of the Surveillance Station. Moreover, you can only work with the camera in the Surveillance Station of the TS-109Pro II through Internet Explorer 6.0 or higher, which is not convenient for users who prefer other browsers.

Still, although the TS-109Pro II is inferior to the Synology DS207+ in performance, its results are quite good for its class.
