Samsung’s UFS 5.0 storage is here, twice the speed of today’s premium memory

To be precise, Samsung said its sequential read speed reaches 10.8GB/s, while sequential write speed caps out at 9.5GB/s. It did not miss the opportunity to add that these doubled speeds are obviously very good for running demanding, on-device AI applications.

Beyond speed, Samsung also said it has better power efficiency through clock gating and multi-voltage technologies. It lowers the power required to transfer the same amount of data, which the brand said is up to 40% more power-efficient than its own UFS 4.1 storage technology.

It is also 16.7% smaller than UFS 4.1, measuring 7.5 x 13mm, at just 0.9mm thick. These might not matter to many electronic appliances out there, but the smaller footprint is critical to smartphone components that need to maximise every millimetre available within. The reduced size also makes it possible to see the storage made available in previously hard-to-implement form factors, such as smart glasses (XR).

When will we see mobile devices with UFS 5.0 storage?

Samsung said it will begin mass production in Q4 2026. The earliest we’d likely see them on mobile devices is 2027 or later, and that’s still dependent on brands buying and using them.
