After two years, Samsung Semiconductor finally announced the latest UFS 4.0 flash storage solution for smartphones and other electronic devices. Samsung claims that UFS 4.0 storage delivers double the speed of UFS 3.1, its predecessor, while keeping the power consumption in check. To learn more, in this article, we have compiled all the information related to UFS 4.0 and how it compares against its past flash storage standards. We have also shared details about the new SD Express card in case you want to learn more about its specifications and speed. Anyway, let’s go ahead and find out what is UFS 4.0 and how fast storage can be utilized in the 5G era.
In this UFS 4.0 explainer, we have detailed what is UFS 4.0 and compared its speed with UFS 3.1 and past UFS standards. You can expand the table below and move to any section you want.

What is UFS 4.0?
UFS 4.0 is the latest UFS (Universal Flash Storage) standard defined by JEDEC, the umbrella organization that looks over the development of UFS and other microelectronics standards. In January 2020, JEDEC released the UFS 3.1 specs, and the new UFS 4.0 standard has come up after over two years. It promises double the speeds of the previous UFS 3.1 standard.
UFS 4.0 can deliver a sequential read speed of 4200MBps and a sequential write speed of 2800MBps. For your reference, UFS 3.1 is capable of driving the sequential read speed up to 2100MBps and sequential write speed up to 1200MBps. That’s more than double the speed of UFS 3.1, which is amazing.
Here is the speed comparison between UFS 4.0, UFS 3.1, UFS 3.0, and UFS 2.2. As you can notice from the table below, UFS 4.0 is indeed a monumental upgrade over the UFS 3.1
What Phones Will Come With UFS 4.0s Storage?
Currently, none of the smartphone makers have announced smartphones with UFS 4.0. However, Samsung Semiconductor has announced that UFS 4.0 mass production will start in the third quarter of 2022. It basically means that upcoming Samsung flagship phones, beginning with the Galaxy S23 series, will be the first to include the latest UFS 4.0 flash storage in Q1 of 2023.
Following that, we expect flagship smartphones from OnePlus, Xiaomi, Oppo, Google, and other phone makers to also come with UFS 4.0 storage in 2023. As for iPhones, Apple uses NVMe storage in place of UFS due to better write speeds than UFS.
