Single Client Access - NAS Benchmarks
Evaluation of single client performance in a networked environment was done by configuring three drives in RAID-5 in the QNAP TS-EC1279U-SAS-RP unit. Two of the network links were bonded (configured with 802.3ad LACP). Our usual Intel NASPT / robocopy benchmarks were processed from a virtual machine in our NAS testbed. The results are presented in the graphs below.
For almost all workloads, there is no discernible difference between the performance of various drives, indicating that it is the network acting as a bottleneck for single client access. Even when there are differences, it shows that certain drives are better suited for a particular type of workload compared to others. Differences start to appear when there are multiple clients accessing the NAS.

At the current rate, it'll be only a few years before NAND hits parity with magnetic storage in capacity and price.3D (verticle) NAND and Intel's 3D X-Point are going to revolutionize storage as we know it.
X-Point will slowly make NAND a cheap commodity for the consumer sector (abandoned by the enterprise sector for X-Point) and NAND will be so cheap to produce by that point (it's 30 year old technology) that it'll be the common medium. It has already killed virtually every other form of portable storage (floppy disks, tapes, CD/DVD/Bluray, etc) with the only worthy exception being large capacity (2-4TB) 2.5" portable hard disks. It's only a matter of time before 4TB SSD's cost nearly the same as 4TB hard disks, and hard disk platter density is already hit some physical barriers, hence the need for shingled recording and other reliability/performance sacrifices.
But even then, soon,

SSDs aren't for NAS due to pricingIf you put a SSD in, many of the charts would be unreadable due to scaling issues.
Also, if the NAS is used for large number of writes, the SSD reliability would be a factor

Reliability would not be a factor. Large financial institutions are using them for transaction processing, and few things require more write reliability than that.FunBunny2 - Tuesday, September 8, 2015 - link
The advantage of SSD is, according to legend at least, a more consistent life time: just retire them at x% of warranty, less infant mortality and random death (getting run over by a bus, in human terms).MrSpadge - Monday, September 7, 2015 - link
The strong DAS performance bodes well for the new 6 TB Black model, which is probably physically similar but with different firmware settings.Wwhat - Monday, September 7, 2015 - link
Why is the article listing the WD red pro with the addition 'star NAS'? Since when is WD using the 'star' term? I can't imagine them doing so, and especially see a company market something with 'red star' these days :)A quick web search shows only anadtech adds 'star' the the name.

disappointing performance. basically every other nas drive on the market is faster than these. HGST and Seagate dominating.star-affinity - Tuesday, September 8, 2015 - link
According to the benchmarks in this article – as a DAS drive the WD Red Pro seems nice – but it for some reason seems not as good when used as a NAS drive, agreed on that.Arbie - Monday, September 7, 2015 - link
We want eight and we won't wait.Gigaplex - Monday, September 7, 2015 - link
Colour me disappointed that there is no analysis of acoustic behaviour. My NAS is by far the loudest device in my room due to the 4 WD Red (non pro) drives in it, and they're supposed to be one of the quietest drives available.
