Two years later, Samsung Semiconductor announced the latest UFS 4.0 flash storage solution for smartphones and other electronic devices. Samsung claims that UFS 4.0 storage offers double the speed of its predecessor UFS 3.1, while keeping power consumption in check. To know more, in this article, we have compiled all the information related to UFS 4.0 and how it compares against its previous flash storage standards. We have also shared details about the new SD Express card in case you want to know more about its specifications and speed. Nonetheless, let’s go ahead and find out what UFS 4.0 is and how fast storage can be used in the 5G era.
UFS 4.0 Storage Standard Explained (2022)
In this UFS 4.0 explainer, we have explained in detail about UFS 4.0 and compare its speed with UFS 3.1 and previous UFS standards. You can expand the table below and go to any section you want.
What is UFS 4.0?
UFS 4.0 is the latest UFS (Universal Flash Storage) standard, defined by JEDEC, which sees 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 out after two years. It promises to double the speed of the previous UFS 3.1 standard.
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 generation of UFS 4.0 storage has a Maximum bandwidth of up to 23.3Gbps per lane, which is twice the speed of UFS 3.1. And since UFS comes with a full-duplex interface (compared to eMMC), it can read and write simultaneously, offering dual-lane data transmission.
Can provide sequential read speeds of UFS 4.0 4200Mbps and sequential write speed of 2800MBps. For your reference, UFS 3.1 is capable of driving sequential read speeds up to 2100MBps and sequential write speeds up to 1200MBps. That’s more than twice the speed of UFS 3.1, which is amazing.
Not only that though. Power efficiency is one area where Samsung has greatly improved the UFS storage standard. UFS 4.0 Standard Consumes 46% less power than UFS 3.1, While offering 2x performance. This means you’ll have much faster storage without reducing the battery life of your next flagship smartphone. Effectively, for each mA, it can deliver a sequential read speed of 6.0 Mbps.
In terms of dimensions, Samsung has size kept compact, keeping in mind the design convenience for smartphones and other electronics. The maximum dimensions of the Samsung-developed UFS 4.0 storage are 11 mm in length, 13 mm in width and 1 mm in height. Samsung has also stated that the 4.0 standard 1TB. will have the capacity to (UFS 3.1 only supports up to 512GB), which is more than enough for portable devices.
Speed Comparison: UFS 4.0 vs. UFS 3.1 vs. UFS 3.0 vs. UFS 2.2
Here is a speed comparison between UFS 4.0, UFS 3.1, UFS 3.0 and UFS 2.2. As you can see from the table below, UFS 4.0 is actually a significant upgrade over UFS 3.1.
|UFS 4.0||UFS 3.1||UFS 3.0||UFS 2.2|
|sequential read speed||4200Mbps||2100Mbps||2100Mbps||1000 Mbps|
|sequential write speed||2800Mbps||1200Mbps||410 Mbps||260Mbps|
|read random||don’t know yet||100,000 IOPS||63,000 IOPS||58,000 IOPS|
|write random||don’t know yet||70,000 IOPS||68,000 IOPS||50,000 IOPS|
Which phones will come with UFS 4.0s storage?
Currently, no smartphone maker has announced a smartphone with UFS 4.0. However, Samsung Semiconductor has announced that UFS 4.0 mass production will begin in the third quarter of 2022. This basically means that the upcoming Samsung flagship phone, which debuted at Rs. Galaxy S23 SeriesThe first to include the latest UFS 4.0 flash storage in the first quarter of 2023.
After that, we expect flagship smartphones from OnePlus, Xiaomi, Oppo, Google and other phone makers to also come with UFS 4.0 storage in 2023. For iPhones, Apple uses NVMe storage in place of UFS due to better write speeds than UFS.
