UFS

Universal Flash Storage (UFS) is a storage interface standard designed for mobile devices, aiming to provide high-performance, low-power storage solutions. UFS technology was developed by JEDEC (Solid State Technology Association) and is widely used in consumer electronics such as smartphones, tablets, and VR/AR devices.
Compared to traditional eMMC storage, UFS offers significant performance advantages. For example, UFS is much faster than eMMC, WITH JEDEC UFS 3.1 standard having an interface speed of 2.332 GB/sec, which is almost six times faster than the 400 MB/sec of eMMC 5.1. In addition, UFS supports full-duplex data transmission, allowing simultaneous read and write operations, while eMMC only supports half-duplex technology. UFS also supports higher storage densities, ranging from 32 GB to 1 TB, while eMMC typically offers capacities from 4 to 128 GB.
