In 2020, Samsung released Universal Flash Storage (UFS) 3.1, promoting it as the storage solution that will fully use the forthcoming 5G technology. It has reasonable speed and efficiency gains over the previous UFS 3.0 and has subsequently become the standard for Android handsets.
That's about to change, as Samsung has unveiled its new UFS 4.0, which boasts significant improvements over its predecessor.
The board of directors of the Joint Electron Device Engineering Council (JEDEC), a global organisation that produces open standards for microelectronics, has approved UFS 4.0, according to Samsung. It will have double the sequential read and write capabilities of the previous generation, with rates of up to 4,200MB/s and 2,800MB/s, respectively. This increase is credited to the company's sophisticated 7th-generation V-NAND and proprietary controller.
The UFS 4.0 is projected to go into mass production in the third quarter of 2022, just in time for the Galaxy S23 series' introduction next year.
With a sequential read speed of 6.0MB/s per mA, UFS 4.0 is projected to use less power and extend battery life. Samsung claims that it is a staggering 46 percent better than the previous version. It will have a massive capacity of up to 23.2Gbps per lane, making it ideal for 5G phones.
Internal components aren't the only thing that's been improved. External dimensions have been lowered, with the UFS 4.0 measuring 11 x 13 x 1mm for 1TB of storage space. A 512GB UFS 3.1 module, by example, measures 11.5 x 13 x 1mm.
