Samsung reveals its first UFS 5.0 storage solution, could debut with the Galaxy S27

Samsung has today announced what it claims is the world’s first UFS 5.0 storage chip. It promises sequential read speeds of up to 10.8GB/s and sequential write speeds of up to 9.5GB/s, up from 4.3GB/s and 4.1GB/s for the current UFS 4.1 storage. which happens to be the fastest storage grade currently used in production smartphones.

Samsung says the UFS 5.0 chip is 40 percent more power-efficient than UFS 4.1 thanks to clock gating and multi-voltage tech. The chip itself measures 7.5mm x 13mm x 0.9mm, which makes it smaller than its predecessor, too.

Higher throughput usually helps out two places on current smartphones: app launch times and on-device AI, which more and more depends on fast data retrieval over brute CPU power alone. Samsung announced mass production of UFS 5.0 chips will start in Q4 2026, with storage up to 1TB available at launch.

Samsung also just revealed that it’s working on the Exynos 2700 chip, which we expect to power (at least) some Galaxy S27 devices. Leaker Ice Universe tweeted from X that the Exynos 2700 will natively support UFS 5.0, making the Galaxy S27 one of the first phones to ship with the new storage standard. Samsung hasn’t confirmed UFS 5.0 for the Galaxy S27. The S27 isn’t expected to arrive until early 2027, the same time when the chips are expected to go into production in Q4 2026.
