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.

PUSH can write 2 bytes in 11 cycles and POP can read 2 bytes in 10 cycles. Thus the theoretical maximum speed write is 5.5 cycles/byte and maximum speed read is 5 cycles/byte. This means that 10.5 cycles/byte is the best we could possibly do.
