OK, that problem won't bite me again.

I've replaced the broken SSD by an old harddisk, and included it in the backup configuration. I ordered two new SSDs, same size, same model, same brand.

Yesterday, I spend a day juggling with four SSDs, a HDD, the on-board RAID-capable SATA controller on my mainboard, and a few old SATA controllers. After a bit of fiddling, I now have set up the two new SSDs as a RAID-1 used as the data drive. The two old SSDs, that also happened to be a pair of same size, same model, same brand, are set up as another RAID-1 used as the system/boot drive. Data from the old data SSD and the HDD was copied to the data RAID before creating the system RAID. Then, I created a new system RAID from the old data SSD and the HDD, copied the working operating system from its SSD to the RAID, disconnected the system SSD, and booted from the system RAID. Finally, I ripped out the HDD, degrading my fresh system RAID, and replaced it with the old system SSD.

Now, any single SSD may die, and I will still be able to use the PC. All I will have to do is to order a replacement SSD and swap it for the then-broken SSD. I know that this will work, because ripping our the HDD at run time was part of the way I migrated to the RAID setup.

If two SSDs in the same RAID will die within short time, I still have a backup, but restoring that will take some time.

I'm considering repeating that process on my machine at work. That machine is basically a copy of my main computer, using a slightly newer mainboard and a slightly faster CPU. And it has no backup at all.
