Two SD Cards lost writing ability less than a year

[sani]

Hello,

I use my raspberry pi 3b+ less than a year.
For this time, my 2 SD cards lost the ability of writing.

May be the reason of this in the raspberry pi? May I check anything for getting know where the issue is?

Model: raspberry pi 3b+
SD card: Samsung Evo 32gb
Power supply: 5v 3a
Connected devices: bme280, cc2531 USB stick

I use the raspberry with home-assistant, mosquito and zigbee2mqtt services.

Home assistant uses a database.
It looks like limiting logging can help. That would make sense.

I believe things like Volumio use a virtual RAM drive for any swap and active data files. Periodically copying the files to the permanent storage.

But the use case for Volumio is very little new data to catalog and store. ( mostly user preferences )

Flash memory has a limited amount of rewrites. You must balance your backup needs with the media replacement frequency.
