WebSep 7, 2024 · ESP32s use NOR flash storage, which is usually rated for between 10,000 to 100,000 write cycles (100,000 seems to be the standard these days). Flash can't write single bytes; instead of writes a "page" of bytes, which I believe is 256 bytes. So each 256 byte page is rated for at least 100,000 cycles.
