8Gb NAND flash?

I have a custom ESP32 pcb with 16MB flash and 8MB PSRAM.
Is there any reason why I can't add a 3rd SPI connection to a 8Gb NAND flash chip for additional storage? Can I mount these like an sd card or does every chip have a different access protocol?

Thanks

See
this library. The biggest chip tested with that library is 1Gb (128MiB) so your choice is either to use that or do some research and experimentation for the 8Gb chip.

Thanks Peter I will check out your library.
I'll get an 8Gb chip and give it a try, will open a PR if it works!

So did it work, or not?
