If it fails, I will just throw in a new SSD and redo the backup. I sometimes delete everything and redo it anyway, for various reasons. In any case, I usually have all copies of all files on the original drive, as local backup on the device and backup on the workstation. And even if those three should fail - which I will immediately know, due to monitoring the systemd job - I still have daily backups on two different, global hosters as well as the seperate NAS. The only case in which all full backups would be affected would be a global destruction of all electronics due to solar storms or a general destruction of earth, in which case that’s the least of my problems. And in case the house burns down, and I only have the daily backups, potentially losing 24 hours of data, that’s also the least of my problems. Yes, generally using Raid 5 for backups is better, but in my case I have multiple copies of the same data at all times, surpassing the 321 rule (by far - 622, and soon 623). As all of my devices are connected via Gigabit, getting backups from eg. the workstation after the PC (with backups) died is just as fast as getting backups from the local PC backup Raid itself. And using Raid 0 is better (in speeds) than just slapping them together in series.
Umm … no. Raid 0 is a hold over from an earlier era when some programs needed mulitiple drives to act as one. It has no redundancy. There is very limited use for Raid 0 with modern drive sizes and most of them are in research where gigs of data are generated with a 10s experiment. If a single drive goes down in Raid 0 the whole volume is lost.
The Raid setup you are describing is Raid 1 (full backup) or 5 (distributed backup). Raid 0 for gaming is worse JBOD. Though the faster read times might mater for HDDs.
Edit: Further reading of your system setup looks custom and amounts to manual Raid 1 over Raid 0+JBOD. It’s also extremely high maintenance. If it works good on you but you could offload your data temporarily and configure the majority of your drives into Raid 6 to drastically reduce your maintenance level and stability/parity.
Raid 0 offers no redundancy though. If any of those three disks fail, you lose the entire volume.
For the sake of backups, switching to Raid 5 would be more robust
