I had this problem with pi 4 after frying several SD cards I found out you can setup read only file system and since then no problems for 3 years now. https://core-electronics.com.au/guides/read-only-raspberry-p...

Boot from a USB SSD instead. I get literally 100x the IOPS over the reasonably fast SD cards I used. Things like apt-get upgrade take seconds instead of many minutes. It’s an entirely different experience.

Get as big of an SD card as you can from a known good company ( I think I have a 256GB card in mine). Turn off as many logging services as you can. You should be able to find several guides on the internet on how to limit writes to the SD card and that combined with a big card with decent wear leveling should last for years, mine has.

Is it possible your SD cards are fake? I did full disk writes till destruction and got 1000 cycles with a Sandisk Ultra (their cheapest line of microSD cards)

That should be enough for 10 years under a typical Pi workload like writing and compacting logs.
