Performance

We have already found out that the DS107+ is a high-quality NAS device with rich functionality. It’s time to check it out in practice now. We’ll take a D-Link DSM-G600 we have tested recently as an opponent to the DS107+. Here is a full list of equipment we’ll use for this test session:

  • D-Link DSM-G600 NAS
  • Category 5e Ethernet cable
  • Intel Centrino notebook
  • Seagate Barracuda 7200.10 hard disk drive (250GB, SATA-2) in the Synology DS107+
  • Seagate Barracuda 7200.10 hard disk drive (400GB, ATA-100) in the D-Link DSM-G600
  • Transcend JF130 USB flash drive (2GB)
  • IOMeter
  • FlashFXP FTP-client

We’ve got a device without a WLAN module today, so we are only going to measure the speed of the NAS’ Gigabit Ethernet port. As in our tests of the DSM-G600, 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.

No comments seem to be necessary. Although the DSM-G600 can perform more disk operations per second (by 10%), the disk subsystem of the DS107+ is far superior (by 100% almost) to that of the DSM-G600 in data-transfer speed.

The next test is about the integrated FTP server available in both NAS devices. FTP remains an important data-transfer protocol, unfortunately not implemented perfectly in many devices. We measure the data-transfer speed not only for the integrated HDD but also for an external device, a USB flash card. The speed of writing to the FTP server is measured using a large file only to find the peak write speed. The speed of reading is a much more important parameter for everyday applications, so we’ll test the speed of downloading all basic types of multimedia content. We’ll download files with FlashXFP and mark the average download speed reported by the program in the server connection log. We’ll use the following content types: a 700MB DivX movie (L), a 200MB folder with MP3 files (M), and a 200MB folder with photographs (S).

The NAS device from Synology wins this test providing a completely different level of performance. The speed of reading a large file from the integrated FTP-server is especially impressive as it approaches the read speed of the HDD itself.

With its performance in the tests the DS107+ proves that it is really worth every cent of its price.
