When it comes to the type of storage that powers smartphones, UFS (Universal Flash Memory) has become the norm.It has even replaced eMMC storage in most budget smartphones.Now, Samsung hopes that by usingUFS 4.0Storage standards take it to the next level.

 

So, what is the new feature and how does it outperform its predecessor?we'll take you through the newUFS 4.0technology, itUFS 3.1How does it compare, and how good it could be for the future of Android smartphones.

What is UFS 4.0?

 

UFS 4.0 is the next generation of UFS technology.This new UFS 4.0 storage standard arrives two years after Samsung announced it and promises twice the performance.

Using its seventh-generation V-NAND flash technology and an in-house proprietary controller, Samsung designed UFS 4.0.It also incorporates the UniPro 2.0 transport layer (which connects components to the chipset to transmit data) and the MIPI M-PHY v5.0 physical layer.

It's complicated, so let's break it down. NAND flash is a storage technology that retains data without power. V-NAND is an improvement over NAND technology because the cell planes are stacked vertically.This results in increased speed, longer lifespan, and lower power consumption.Samsung has incorporated this technology into UFS 4.0, although the precise proprietary controller it uses is unclear.

UFS 4.0 and UFS 3.1 How does it compare?

UFS 4.0 is a major improvement over UFS 3.1. UFS 4.0 can provide sequential read and write speeds of 4200MB/s and 2800MB/s, respectively.By comparison, UFS 3.1 offers sequential read and write speeds of 2100MB/s and 1200MB/s, respectively.

In addition, UFS 4.0 has a maximum bandwidth of up to 23.2Gbps per channel, which is twice the speed of UFS 3.1. The UFS interface supports dual-channel transmission, allowing simultaneous read and write operations.This improvement benefits 5G smartphones, automotive applications, and AR/VR devices that require a lot of data processing.

In terms of power efficiency, Samsung has made significant progress with UFS 4.0.It consumes 46% less power than the previous generation while still delivering twice the performance.

Samsung has kept its compact size up to 11 x 13 x 1mm to improve its compatibility with smartphones and other electronic devices.In addition, Samsung said that UFS 4.0 supports a maximum capacity of 1TB, which is double the 3.1GB of UFS 512.This storage capacity is more than enough for smartphones and portable devices.

What does UFS 4.0 mean for the future of Android smartphones?

 

Samsung Semiconductor has announced that mass production of UFS 4.0 will begin in the third quarter of 2022.Starting with the Galaxy S23 series, the upcoming top-of-the-line Samsung smartphones will feature the latest UFS 4.0 technology.We're likely to expect OEMs like OnePlus, Xiaomi, Google, and Oppo to adopt this next-gen storage standard by 2023.

Adding UFS 4.0 to Android smartphones will bring them even more functionality.Many companies are adopting 5G technology, which requires faster read and write speeds.As the number of 5G-enabled devices increases, UFS 4.0 appears to be the right technology to deliver the required performance.

UFS 4.0 is the next flash storage solution

Most smartphone makers use Samsung's high-end UFS storage solutions, so the latest UFS 4.0 offers a compelling option for upcoming Android smartphones.
