Also you should have backups of all of your data anyway.
I run crashplan on my laptop and it pushes backups to my server which has parity protected raid via unraid.
You should always have backups of data, and also raid is not backups.

Mirroring a drive will not protect your data from accidental deletion, viruses, etc. since the mirror will also have the same problems.

One good backup strategy I can recommend you for instance is 3-2-1 which stands for 3 copies on two separate locations and 1 offline.
Hope this helps and feel free to ask any questions you may have.
I currently have a Synology NAS (4 drives). I have had a decent amount of occasions where it was less than easy to use, unresponsive, or simply had a drive fail on me. Of course, it was fine that one drive failed because I inserted another and it rebuilt the data as it should. So maybe one day I will either look for something a lot more responsive and reliable or build my own server computer. The problem with the latter options is it is often more costly and I want to keep it in a small form factor with highly reliable software.
The other thing I would like to do is find places online to backup various data. For example, I can have all my photos and videos go to one location, while my documents live elsewhere (including design files). And somewhere else for my music files. Obviously, I believe that would lead to multiple solutions. But, I have run into a lot of issues where sites don't store the original file type and instead downgrade it (like with photos or music) or make things very inaccessible. I was contemplating to continue to use Flickr for photos, Google for my own ripped CD's, and am still looking for a long term place for files and videos.
