Summary: I have upgraded to this unit from a WD MyBook Live, which I've found to be too slow and unreliable for my home media set up. The QNAP is working well so far. I installed one WD Red 2TB drive, which was super easy. Red drives are recommended because they run at a low temperature for NAS systems. The second drive, if I install one, has additional connectors to fiddle with but doesn't look beyond me.
Summary: Very easy to set up and configure. I use it as a shared network drive, which works very well with windows 8 File History (Start -> File History). I didn't have much luck with setting it up as an ISCSI drive (so it appears like a local hard drive attached to your computer). I found ISCSI + windows 8.1 + file history caused random lock-ups of my laptop (both when connected to my home network and away).
I've had this unit since April and am pleased I went with it

Summary: I've had this unit since April and am pleased I went with it. Setting up the unit was pretty straight forward. I'm probably using it a little different to most folks so just wanted to relay my set up and functionality I have used it for. I initially installed 2 x 4TB HDDs in a RAID configuration. However, as I like to keep backups of my files on additional USB drives off site I changed this.
Summary: Having a few different NAS units, including a few QNAP, I bought this for a wee unit for occasional (Semi) portable use. Frankly this was a mistake, as I am only competent at Linux, not an expert (see other reviews). So it took several wasted weeks to get this unit configured to work any where close to a sensible level, and I am stuck at mirroring (i.e. needing 4T to get a usable 2T) as JBOD defeats the object of NAS.
Summary: We've since bought another as we were so impressed. As a basic functional NAS it does the job very well, as an extended function device it's also great. So many extra features you may find it offers a bit too much and like us you just ignore them. QNAP clearly are actively developing their software with regular new features and software released and with the iOS app to allow basic controls when your computer isn't on , this does the job exceptionality well.
Summary: Superb device, note - it is often cheaper to buy external housed drives for this and take them apart - cheaper than a bare drive !! - and you get a couple of spare usb 3 3.5 cases if you do that. QNAP is fantastic, the firmware and apps are first class. Just the job.
Summary: I've given this 2 stars because it is possible that it might be OK for an expert user. From my point of view however it scores zero stars. It was fiddly but not difficult to install the new WD Red hard drives that I had also bought from Amazon, and the Cloud-based initialisation works beautifully. However the product cannot actually be used until a host of other settings have been made, because nothing is enabled by default.
