Document read/write performance and CPU overhead compared to eMMC.
As the result of AI demand, eMMC is already difficult to source and major vendors will be stop production in the coming years. For automotive companies that plan many years in advance this presents a challenge.
SPI NAND does not provide the capacity of eMMC so any viable design would need to include multiple SPI NAND parts with dedicated chip selects. We won't be able to test this configuration but it would be good to know how it could he handled in Linux, perhaps at the filesystem level?
Tests
Both EROFS and UBIFS support various compression algorithms.
