I have been running a Raspberry 2 cluster for 10 years.

A few weeks back the first SD card to fail got so corrupted it failed to reboot!

My key learning is use oversized cards, because then the bitcycling will wear slower!

I'm going from 32GB to 256/512/1024!

That said "High Endurance" cards are a scam, they fail way quicker than regular cards!

All SD cards except SanDisk have latency problems. There is no competition.

If you can get SLC SD cards use them for workload instances = no db or file storage.
