The quality exceeds all expectations, I recommend to buy.

I've been using them for a couple of years. Familiarize yourself with all its features and functions.
Already there was a death of one disk (has been replaced). And it still works well. Until I was let down.
In mine now there are 2 disks for 12Tb (Raid 1) and 2 disks for 10Tb (Raid 1) both HGST (advice, do not buy them. There is no guarantee for them in 2022. I already got it). So it supports big disks.
I use it only as a storage for files and backups. Which he encrypts at night and uploads to cloud storage. For secure backup. In case something happens to my devices at home.
I'm a little surprised by the negative reviews. Since this is the initial line of QNAP.
And want something more from him than a file archive. This is strange in my opinion.
It copes with the task of a simple home archive (backups / files) perfectly.
As a media station it is too weak. It has an AL212 processor with 2 cores 1.7Ghz. The memory is only 1000MB. And the system itself consumed about 15-25% . Usually I have used 50-60% of the memory .
What happens when one of the drives dies in Raid.
If you set up informing, it can send you Email or SMS (if you are subscribed to some SMS service). Plus, the red light starts flashing. If notification is not configured. It just blinks. (the bulb is not very noticeable)
Next, let's go buy another disk. We take out the faulty one. After a couple of minutes, we insert a new one. And wait until he finishes the Rebuild raid. That's all. You don't even need to turn it off.
There are no problems with informing or replacing the disk. As stated in the reviews. I don't know what went wrong with the person.
About the admin. I set everything up once. And I don't go there anymore. I just have nothing to do there. Yes, Qnap for some reason allows you to put Video Station, Music Station, Virtualization on this model. If you put it. It will just wildly slow down and swap. So if you don't want it, delete it if it's worth it. And don't bet.
In my opinion. For this money. Pretty decent NAS.
I wanted to describe more, but  set a limit on the message.

Pros

1) Low price tag compared to the same Synology . 2) The admin panel is quite nice and convenient 3) Ability to do Raid 1 4) It is possible to add a Hot Spare Disk. 5) There is disk encryption 6) Very flexible allows you to customize informing (Email, SMS .). 7) Supports large drives (12Tb, no longer tested) 8) Able to synchronize files with clouds in all directions. 9) You can make different users with different rights. 10) There is Microsoft Networking, Apple Networking, NFS 11) You can log in from the admin via SSH. (For crontab or scripts) 12) There is a dynamic Amazon service. To access from the Internet…

Cons

1) HBS does not have built-in SSH Rsync capability. Such rsync is possible only via SSH from the admin . 2) There is no way to expand the memory (all chips are soldered). She's really small. 3) The processor is weak. But for the money to want more strange. 4) Very slow software Qsync (refused to use it).
