QNAP TS-669 PRO 6-Bay SMB NAS Review - Benchmarks - Multi-Client Test

Benchmarks - Multi-Client Test


The Intel NAS Performance Tool (NASPT) is an excellent way to determine NAS performance in a single user environment. Any review that only uses NASPT assumes that only a single computer will access the target NAS at one time. We took issue with this method of testing and spent over a year designing, building, programming and finally validating the TweakTown Multi-Client Test.


The test uses Microsoft Office data recorded to traces and played back to the NAS from up to 120 client Windows 7 installations (clients). We record total throughput of all clients and average response time per client.


Over time we'll populate the two multi-client charts with several NAS products from a span of categories. The products range from a dual Xeon server with 2x 10GbE to a 2-bay NAS with a single gigabit Ethernet connection. The products will fall into their performance categories based on performance and not marketing material or opinion.






In our multi-client test, we observed a noticeable improvement in performance from the TS-669L to the TS-669 Pro, again mainly due to the new firmware.


The peak throughput was considerably higher and the highest performance came later in the test. That means more clients can use the NAS in an office environment before reaching peak performance.







The new firmware reduced the latency by a large margin as well. This means the firmware is more responsive when working with files on the NAS in an office environment.
