File Copy Test (8.83GB)
Intel NAS Performance Toolkit v1.7.1
Power Consumption


All of our comparison NAS servers are tested using a single Gigabit Ethernet link with Jumbo frames disabled, and are connected to our client machine and network via a Netgear GS108 switch.

Taking a look at a basic usage scenario, our file copy test involves moving a mixed assortment of files totalling 8.83GB in size from our client to the NAS. The result is recorded in MB/s.

Our second benchmark - NAS Performance Toolkit, developed by Intel - is a file-system exerciser specifically designed to provide performance comparisons between NAS devices. Intel's utility focuses on user-level performance using real-world workload traces gathered from typical digital home applications such as HD video playback and record. Intel NASPT reproduces the file-system traffic observed in various traces onto a chosen storage device and records performance in MB/s.

Last but not least, we measure NAS power draw during three states; under load, idle and standby mode if applicable.

Readers should note that our usual hard drives - 1TB Samsung HD103SJs - have bitten the dust. 4TB WD Red hard drives (model WD40EFRX) have been introduced as a replacement and these drives will be used in all future NAS reviews. The Qnap TS-453 Pro, Synology DS115, Synology DS414j and Thecus N4310 are the first units to be tested with the revised WD Red configuration.

We've kept benchmark results from multi-bay NAS units, but of course it's the single-bay comparison we're interested in seeing: Synology DS115 vs. WD My Cloud. The hardware suggests that the former will be comfortably quicker, so let's see if the benchmarks concur.
