According to our NAS expert
You'll have access to your media files from every network device with the Qnap TS-251A. Easily save videos, music, and pictures from the laptop, desktop, telephone, or tablet you connected to it, wherever you are. Connect your camera via the USB port with the NAS to save your pictures without the intervention of a computer. The network drives from the X51A series can just as easily be used as an external hard drive. The drive is also suitable as backup for photographers or designers because you don't need any network knowledge. With the Qnap apps, you determine which extra functions you'd like to allocate to the TS-251A. Use it as mail server or as media center. This way you'll stream movies in 4K to your TV. The NAS filters a backup on empty files, so these don't take up unnecessary space.

I bought the Qnap as a central backup for myself and the devices in my family. As such, it also works nicely. The only thing that annoys and amazes me is the disk activity when no one is connected to the system. We've only had a small amount of data stored on the Qnap and yet it's stomping and rattling as if an entire company is processing data. I honestly don't know how to interpret all that activity, maybe I should dig even deeper into the configuration. But the unclear activities of the Qnap and the noisy hard drives mean that we often have the Qnap turned off, the Qnap is in the room. And of course, turning it off is not the intention of this system.
I have extensive experience with computer hardware and had done my homework before purchasing a NAS. But I'm not really impressed with the Qnap. I am afraid that this system will be used as a glorified external hard drive as the situation is now.

I wanted a backup that can withstand disk rot and because it has an HDMI connection I thought "why not a media server and redundant backup system?". Especially after you're fiddling with disks and your dropbox or gdrive syncs badly and that sort of thing.
It is PACKED with apps and features that you can activate and deactivate. With a little data center experience, this all came across very confident. And I was amazed at the level of professional features that run on this small tray. You do have to take your time to configure it. And think about how you're going to do everything.
EVEN VMWare and virtualization is supported, but unfortunately the software tells me to install more RAM.
In short, this is really your "personal cloud", I'm considering buying a 2nd and putting it in another location to sync them together.

Great NAS server. Bought primarily for Backup and media server to mobile devices. Is my 2nd NAS next to my WD mybook cloud. Qnap has better mobile apps and better organization. The on the fly transcoding is a bit disappointing for HD. Haven't tested 4K yet. Possibly due to internet connection.
