Samsung roadmap reveals the UFS chips coming to the flagship Galaxy S25, S26, and S27 lines،
After using its own Universal Flash Storage (UFS) 4.0 chips for the flagship Galaxy S23 and Galaxy S24 series, a roadmap published by Samsung Semiconductor reveals what the manufacturer has planned until 2027. UFS offers a fast storage option and reliable for smartphones that will also load apps quickly, access data faster, and provide an overall better experience than previous storage options used a decade ago, such as integrated media cards (eMMC).
In May 2022, Samsung introduced UFS 4.0, noting that it offered bandwidth of up to 23.2 Gbps per lane, double that of UFS 3.1. At the time, Samsung said UFS 4.0 was “perfect for 5G smartphones requiring huge amounts of data processing.” UFS 4.0 delivers sequential read speeds of up to 4.2 GB/s and sequential write speeds of up to 2.8 GB/s.
Samsung's 2024 foldables, due this summer, the Galaxy Z Fold 6 and Galaxy Z Flip 6, will both likely use UFS 4.0 as they did in 2023. The 2022 foldables (Galaxy Z Fold 4, Galaxy Z Flip 4 ) were using UFS 3.1.
Samsung Semiconductor UFS Roadmap
Samsung Semiconductor's roadmap shows that UFS 4.04-lane will arrive next year and it is quite possible that Samsung's flagship Galaxy S25 series will be the first smartphone to launch UFS 4.04-lane. A graphic posted on the social media platform Weixin (via SamMobile) from the Samsung subsidiary shows that sequential read speeds will almost double to 8 GB/s. The same 4.04-lane UFS chip will be used on the Galaxy S26 series.
And in 2027, the debut of UFS 5.0 will take place on the Galaxy S27 range with a sequential read speed close to 10 GB/s. According to Samsung, improving sequential read time reduces model loading time to improve the UX (user experience) of a phone line.
Mass production of the UFS 4.04 lane will begin before 2025 and will combine two UFS controllers for faster sequential read speeds. Improving UFS storage capacities and increasing UFS speed will help Samsung offer more AI capabilities for its smartphones, which is quickly becoming a major selling point in the market.
