Some modern smartphones already use UFS 3.1 storage that offers read/write speeds that are comparable to a decent SSD. But soon you could start to see mobile devices with UFS 4.0 storage that offer speeds that are competitive with a fast SSD.
Samsung has already introduced the first UFS 4.0 storage solution, which the company says will deliver sequential read/write speeds up to 4,200 MB/s and 2,800 MB/s, respectively.
According to Samsung, the new UFS 4.0 storage solution supports speeds up to 23.2 Gbps per lane, for 2X faster read speeds and 1.6X faster write speeds than UFS 3.1 storage. At the same time, the company is promising a 46% improvement in power efficiency.
The new UFS 4.0 storage modules measure just 13 x 11 x 1mm and offer capacities up to 1TB.
While the new storage solution complies with JEDEC’s UFS 4.0 standard, Samsung says it’s based on the company’s 7th-gen V-NAND technology and uses a proprietary controller. So while we may see other companies offer their own UFS 4.0 solutions, this particular version will most likely be used in Samsung’s own devices and/or sold to other companies for use in other products.
In addition to smartphones, Samsung envisions its UFS 4.0 storage being used in virtual reality, augmented reality, and automotive solutions.
Mass production should begin in the third quarter of 2022, which means we could see phones, tablets, and other devices with UFS 4.0 storage by the end of the year.
