This article will dissect the architecture, benchmark numbers, real-world performance, and future-proofing aspects of these two storage standards. By the end, you will understand why UFS 2.2 is the clear winner and why manufacturers still cling to eMMC 5.1.
UFS is a newer, more advanced standard designed specifically for high-performance computing in mobile devices. Unlike eMMC, UFS uses a serial interface with dedicated read and write channels.
eMMC is a storage technology derived from the SD card standard. In an eMMC chip, the controller and the NAND flash memory are soldered together into a single package. It uses a interface (specifically the parallel interface of the JEDEC standard).
