My best guess (not in the community or anything) is that leather does better at being durable—especially if you treat it well and condition it regularly?—than cloth and plastic-leather alternatives, which break down. I know leather is meant to be very durable and have good “properties,” but I can’t be specific.
To clarify, running Plex is easy; running Matrix is very NOT easy… But being a NAS was the easiest part, by far. Stick the drives in, turn on, follow the short manual that came with it to configure, and let it do its thing.
I had considered running a DIY for years, and eventually just caved and bought a Synology 1522+ NAS. It lets me run my Plex server and Matrix server, and it just handles all the config and updates for me easily.
The decision was that I wanted to backup my hobbies, not have backup BE my hobby.
It’s very good at [whatever you’re willing to program it to be good at], for sure!
