Most SD cards for sale are not suitable for write-intensive random-access workloads. However, they do make SD cards that are intended for this, I've had very good luck with cards marked "high-endurance." They cost more, but they work.

I've always been amazed that the Foundation never mandated the use of validated brands or types of SD cards.

Not that it matters much to me, I've had to retire all of my Pis earlier than the 4. It seems that all of my Raspberry Pis prior to the 4 all had some sort of design issue with their power regulation. After a couple years of constant operation, they just start locking up randomly around once every day or so. I've had everything from a Pi 1 through 3 exhibit this behavior. I spent WEEKS troubleshooting this and conclusively ruled out wonky SD cards, power supplies, connected devices, proximity to other equipment, and every other factor I can think of. I found many threads with other people reporting the same issues but the Foundation refuses to acknowledge it as a problem. I only run Pi 4's now, and am gradually switching over to Intel N100-based systems for low-power operation.

My money is on the use of a single USB 2 port for power for both of these issues :
