Interesting blog!
Clicked on your NAS article (one of the first linked ones) and spotted an error… you write that Synology NAS boxes don’t use standard RAID, but they do. They have official docs up on how to hook them up to a standard Linux system for disaster recovery (it’s just Btrfs or ext4 on mdadm RAID).
Probably not super relevant for you or most readers, but just thought I’d point it out :)
Yeah Synology is pretty good with that kind of stuff (we use one at work). They’ve really just got a Linux system with custom management tools on top. Of course for DIY purposes, self-building is still cheaper and more flexible though.
