QNAP SilentNAS HS-251+ 2-Bay Passive-Cooled NAS Review

Testing Method

Most of the hardware for NAS testing isn’t an important factor when it comes to benchmarks, most of it comes down to the network infrastructure. I will be teaming the two Intel Gigabit Ethernet ports on my test bench and connect them to my managed switch. The same will be done with the available LAN ports on the NAS, which should give a great testing environment.

As part of the testing, the NAS is connected through a D-Link DXS-1210-12TC managed 10GBase switch and then to our test bench to give the best real world setup test that we can and the NAS itself will be packed with Western Digital’s latest RED NAS drives. Intel’s NASPT software does require us to drop the memory down to 2GB, as using any more would lead to data caching and skew the results.

I will be testing the NAS box performance under each of the RAID options that it has available as well just a single drive. Full volume encryption and shared folder encryption will also be tested where available, to check what impact it has on the performance. The USB 3.0 speeds will be measured with our trusted Angelbird SSD2go Pocket drive.

Network Setup:

We would like to thank our sponsors for supplying us with the components needed for the test system as well as drives.

Software used:

With a device of this sort having so many different applications, Intel’s NASPT software covers all the bases and also gives us a set of results that we will be able to utilize and give a benchmark against other similar systems in the future.

Intel NASPT (Network Attached Storage Performance Toolkit) performs its test by transferring varying sizes and quantities of data to and from the device based on twelve different scenarios.
