Samsung UFS 4.0 storage to offer up to 4,200 MB/s read speeds, 1TB capacity

Samsung Electronics has unveiled its first Universal Flash Storage (UFS) 4.0 solution based on the company’s 7th-generation V-NAND and a proprietary controller allowing speeds of up to 23.2 gigabits per second (Gbps) per lane or double the previous UFS 3.1 solutions.

In more practical terms, Samsung UFS 4.0 storage will deliver a sequential read speed of up to 4,200 MB/s and a sequential write speed of 2,800 MB/s, corresponding to about 2x and 1.6x faster speeds over UFS 3.1 storage.

Samsung also claims that power efficiency has been enhanced with a sequential read speed of up to 6.0 MB/s per milliampere (mA), or about a 46-percent improvement over UFS 3.1. An advanced Replay Protected Memory Block (RPMB) is integrated into the chip to store important personal data that can only be read or written through authenticated access, and whose design is said to be 1.8 times more efficient.

Samsung UFS 4.0 storage will be offered in a 13 x 11 x 1mm package and be found in 5G smartphones, as well as automotive and AR/VR applications. Mass production is expected to start in Q3 2022 and be sold in various capacities up to 1TB. More details may be found in the announcement. I was also going to redirect readers to JEDEC website for the UFS 4.0 specification, but it does seem to have been published just yet.

  1. Very cool.
    This will likely mean things like SSDs with larger capacity and likely also that eMMC / NAND Flash in some cases will be replaced by those ICs (if/when they are affordable and if that particular CPU/microcontroller supports the interface used).

    1. No. SSDs don’t use eMMC, they use NAND, and it’d be pointless to replace NAND with UFS. UFS is just a package with NAND and a small controller in the same thing, so what would the point be in slapping those on an SSD? It’s far better to just go with multiple NAND-packages and a single, more capable controller handling all the NAND.

      1. I would believe Jens was talking about storage density only: ‘up to 1TB’ ‘in a 13 x 11 x 1mm package’.

  2. Next generation phones will get it. Hope next sbc will start to get UFS 3.1!
