Samsung’s UFS 4.0 brings 4.2GB/s speeds

Samsung has just revealed that they have developed the industry’s highest-performing Universal Flash Storage (UFS) 4.0 storage solution, doubling the previous mobile storage speeds (twice as fast compared to UFS 3.1 at 11.6Gbps).

UFS 4.0 offers a speed of up to 23.2Gbps per lane, double that of the previous UFS 3.1. That much bandwidth is perfect for 5G smartphones requiring huge amounts of data processing, and is also expected to be adopted in future automotive applications, AR, and VR as well. With Samsung’s advanced 7th-generation V-NAND and a proprietary controller under the hood, UFS 4.0 will deliver sequential read speed of up to 4,200MB/s and sequential write speed of up to 2,800MB/s.

Samsung added that UFS 4.0 is also more power-efficient (by 46%) and comes in a more compact package (dimensions: 11mm x 13mm x 1mm) with storage capacities of up to 1TB. Mass production of UFS 4.0 internal storage for smartphones will begin this July 2022.
