Samsung has made substantial claims regarding the benefits of UFS 4.0 since its announcement last year. The company claims that the new UFS 4.0 chips are twice as fast as its older UFS 3.1 memory, with sequential read and write speeds of up to 4,200MB/s and 2,800MB/s, respectively. Additionally, the new silicon is 46% more energy-efficient, which may result in longer battery life for phones utilizing this technology.
