What is UFS 4.0 Storage and How Fast Is It Compared to UFS 3.1?

May. 5, 2022

After two years, Samsung Semiconductor finallyannounced the latest UFS 4.0flash storage solution for smartphones and other electronic devices. Samsung claims that UFS 4.0 storage delivers double the speed ofUFS 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 thenew SD Express cardin 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 the5G 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.

Samsung Semiconductor has implemented the UFS 4.0 standard with its proprietary controller and 7th-generation V-NAND technology to bring the UFS 4.0 storage solution to the masses. It has also deployed MIPI’s M-PHY v5.0 physical layer specification and the upcoming UniPro v2.0 transport layer specification.

Samsung claims the new-gen UFS 4.0 storage has amaximum bandwidth of up to 23.3Gbps per lane, which is double the UFS 3.1’s speed. And since UFS comes with a full-duplex interface (in comparison to eMMC), it can simultaneously read and write, offering dual-lane data transmission.

UFS 4.0 can deliver a sequential read speed of4200MBpsand 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.

That’s not all, though. Power efficiency is one area where Samsung has improved the UFS storage standard by a lot. The UFS 4.0 standardconsumes 46% less power than UFS 3.1,while offering 2x performance. That means you will have much faster storage on your next flagship smartphone without depleting the battery life. Effectively, for every mA, it can deliver a sequential read speed of 6.0MBps.

In terms of dimension, Samsung haskept the size compact, keeping design convenience in mind for smartphones and other electronics. UFS 4.0 storage, developed by Samsung, has a maximum dimension of 11 mm length, 13mm width, and 1mm height. Samsung has also said that the 4.0 standardwill have a capacity of up to 1TB(UFS 3.1 only supported up to 512GB), which is more than enough for portable devices.

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
