Have you had to replace a disk and do a rebuild?
https://www.digistor.com.au/the-latest/Whether-RAID-5-is-still-safe-in-2019/ TL;DR:* ...the rebuilding successful rate is very low even for 4 bay SATA 5 array with 1TB disks. It’s nearly impossible to guarantee a successful rebuilding with this type of disk because of its too high URE. Another alarming fact about URE is: it has no correlation to the drive’s age.* It's obviously worse with consumer drives compared to enterprise drives - I'm not sure what Hetzner provision though. (Sorry for the slow reply - been AFK.)
