What to look forward to: Samsung has lifted the curtain on its next generation of universal flash storage: UFS 4.0. The latest JEDEC standard specification offers several improvements over the current UFS 3.1, including doubling the speed, improved power efficiency, and reduced size.

Samsung says UFS 4.0 delivers up to 23.2Gbps per lane, double the performance of the current UFS 3.1 standard. The 7th generation V-NAND technology will provide sequential read speeds up to 4200MB/s and sequential write speeds up to 2800MB/s. In comparison, UFS 3.1 achieves a maximum sequential read speed of 2100MB/s and a sequential write of 1200MB/s.

Samsung says the additional bandwidth offered by UFS 4.0 will be ideal for 5G smartphones that need to process large amounts of data and are also expected to be used in future automotive, VR and AR applications.

Compared to previous generations, not only speeds have been improved. UFS 4.0 will also have better energy efficiency than its predecessor. A sequential read speed of 6.0 MB/s per milliamp (mA) means a 46% improvement over UFS 3.1, which means smartphone and other device users should get better battery life.

Finally, UFS 4.0 will ship in a smaller 11mm x 13mm x 1mm package (a 512GB UFS 3.1 module measures 11.5mm x 13mm x 1.0mm), meaning more efficient use of that precious internal smartphone space.

Mass production of UFS 4.0, which will be available in various capacities up to 1TB, is scheduled to start in the third quarter of this year, so we should see it appear in late 2022 or early 2023. This probably means the latest storage solution. coming too late for the Galaxy Z Fold/Flip 4, due this summer but likely to be part of next year’s Galaxy S23 series.
