Samsung introduces UFS 4.0 storage with major performance improvements

Universal flash storage has become extremely popular among Android smartphones. Not so long ago, UFS was found only in flagships and high-end mid-range phones. But as the technology has gotten cheaper, it has largely replaced eMMC as the flash storage of choice in budget and affordable mid-range smartphones. UFS 3.1 was announced in 2020 and is currently the fastest storage solution available for Android smartphones. But now it’s time to upgrade.

On Tuesday, Samsung Semiconductor officially announced UFS 4.0, the next iteration of Universal Flash Storage. UFS 4.0 promises major performance improvements compared to its predecessors, UFS 3.0/3.1. For one, the new standard offers speeds of up to 23.2Gbps per lane. This is twice as fast as the 11.6Gbps speed of UFS 3.1.

Read and write performance also sees a big boost, with sequential read speeds of up to 4,200 MB/s and sequential write speeds of up to 2,800 MB/s promised by Samsung. This is made possible thanks to Samsung’s 7th Gen V-NAND and a proprietary controller. Plus, UFS 4.0 is also more power-efficient, offering 46% better power efficiency than the previous standard.

UFS 4.0 is based on the latest JEDEC standard specification, and while it is primarily targeted for smartphones, it is also expected to be adopted by AR, VR and automotive applications.

UFS 4.0 chips will come in even more compact packages and will be available in multiple storage capacities up to 1TB. Samsung says that UFS 4.0 will enter mass production in the third quarter of 2022. This means that we can expect the first batch of smartphones with UFS 4.0 storage to hit the market later this year or early 2023.
