I mentioned earlier that QNAP has a very extensive set of features built into the operating software, but maybe I should have warned you. The S/W feature list is HUGE. Honestly, a lot of us spend the majority of our time analyzing hardware (yeah, I'm guilty...), but when you see all the capability that a modern NAS server can provide, it's pretty amazing. Let's take a long, detailed look, shall we?

QNAP currently only has 2 rack models with the x79 name that has XEON cpus which do have AES-Ni.
But the other X79 models only have Intel I3 cpus, and last i checked they didn't have AES-Ni instructions on them ..... yet your saying otherwise ? Got any references for that ?
However despite that, Jason from QNAP is claiming their tests on the 879U-RP with AES encryption could achieve 100MB/s in both read & write in Gigabit environment.
His a trustable guy so i'll believe that :X but what i doubt is your claim that i3 cpus have AES-Ni ....
ark.intel.com/search/advanced?AESTech=true
Well, I've got some re-writing to do....
FWIW, my initial testing with AES-256 supports Jason's claims. The GbE bottleneck is the dominant factor.
Thanks for pointing this out.
Jason says it does 100 mb/s and that in my opinion is very good. I was worried and confused why they opted for the i3's which are basically almost the same as i5's but without the aes-ni. But from the results, seems my worries were unfounded ? As i was expecting results like these which was an article by tomshardware showing how bad performance was on many NAS brands across the board that didn't use encryption acceleration such as AES-Ni.
##tomshardware.com/reviews/nas-encryption-aes-ni,2873.html
Anyway i wonder if you would be kind enough to add to your review, a chart showing AES 256 encryption performance of the i3 QNAP to help back up Jason's claim. I trust Jason, but other people who don't know him will want proof from third party sites like yours to see if what QNAP claims is true or not.
I'm also interested to know whether the other i3 QNAP models such as the 1079 can achieve the same good results for aes 256 encryption, as well as compare the results with Synology Diskstation DS3611xs which sports a Intel® Xeon® Processor E3-1225 cpu.
And lets not forget conventional hard drives may also be a bottle neck ?
The fastest read and write maximum throughput for a hard drive is Seagate's New Barracuda 3TB (ST3000DM001)

I don't expect to reach the same speeds that QNAP did with (8) Intel SSDs, but I'm betting it will still be way above what the unit does with the Gigabit interface.
For me, i've used 6 x SAMSUNG HD203WI for a long time and they work fine on my QNAP ts-659 pro II.
QNAP and other branded NAS, tend to ignore tler, so it's not critical for these nases when using raid seeing as it's not being used.

however samsung has sold off their hard drive business to Seagate who bought their hd unit out.
So the only other manufacturer that offered some good desktop raid drives was Hitachi i believe which was the Hitachi Deskstar 7K3000 3TB which is a desktop drive that works fine in raid for say a QNAP.

The desktop drives you should be wary about for using raid are western digital and seagate, which intentionally make it problematic in a raid setup, by dropping out very often to make you buy their x2 expensive raid edition drives.
Samsung drives are still being built to the old designs/specs for now, right? Get them while you can, I think....
Sorry but 10GbE =
...
10GbE =lt 1250MBps. 500MBps = 4800Mbps.
Reasonable sound level for a device to be in a server room.
Too loud for home use.
Would like to see aditional testing with multiple clients or larger queue depth. Need to beg someone for some 10GbE hardware.
Wow! What a difference.
