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?

Comments
to the "Cons" in the conlusion:
Why aren't consumer hard disks often the right choice for drive arrays, also a simple RAID-1 ?
I've heard about it before, but didn't find a real explanation. If you activate HDD sleep after xx idle minutes, the maximum hours of operation should be limited. What else?
The consumer drives have an error recovery scheme that can interfere with the RAID controller, calle "Time-Limited Error Recovery" (TLER). There's ton's of info on the web, including the major drive manufacturer's sites about it.
The second factor is that the drive spindles can wear out quickly from excessive vibration when many, many drives are all chattering away in the same rack. So, some drives (WD Black for instance) are approved by the manufacturer in RAID 0 or RAID1 when there are only two drives in the enclosure. This is great news for all the two-bay NAS owners...
By the way: Thanks for the extensive review, Bruce!
Your measured power consumption on the page "insider details" (8 W in sleep mode) was with or without drives installed? In many reviews, the sleep mode consumption with discs amounts to 12-13W, which is on par with the comparable Synology DS-211+.
