How long will data last on an SD card?
SD cards typically hold data for around 1 to 10 years when unpowered, depending on the type (SLC lasts longer than TLC), but this is not reliable long-term archival storage; charge leakage causes data loss, influenced by temperature, so backing up data is crucial, as flash memory degrades with usage and time, with industrial cards offering better retention.Do SD cards stop working after a while?

For average smartphone shots, expect around 2-10 GB, but for high-quality or RAW files, prepare for significantly more storage.Does formatting a SD card delete everything?
Yes, formatting an SD card deletes all data, but whether it's permanently gone depends on the type of format: a quick format just removes the file system index, leaving data recoverable; a full format overwrites the card with zeros, making data unrecoverable.
