The JEDEC Solid State Technology Association announced today that it's close to completing the next version of its Universal Flash Storage (UFS) standard: UFS 5.0. Built for mobile applications and computing systems that need high performance with low power use, UFS 5.0 plans to deliver faster data access and better performance (up to 10.8 GB/s sequential read/write) compared to its predecessor, while staying compatible with UFS 4.x hardware. To hit the highest performance and most power-efficient data transport, JEDEC UFS uses industry-leading specs from the MIPI Alliance to form its Interconnect Layer. This team-up continues with UFS 5.0, which uses the upcoming MIPI M-PHY version 6.0 spec and the UniPro version 3.0 spec. M-PHY 6.0 brings in a new High-Speed Gear 6 (HS-G6), which supports data rates double those of the previous maximum data rate of HS-G5, enabling UFS interface bandwidth of 46.6 Gb/s per lane and supporting up to roughly 10.8 GB/s effective read/write operation for UFS 5.0 over 2 M-PHY lanes.

Currently, UFS's latest specifications date back to December 2024 when JEDEC published JESD220G UFS 4.1, which is an update to version 4.0 published in 2022. The Universal Flash Storage standard provides high-performance embedded storage that uses little power making it a great fit for devices where saving energy is key. This covers computing and mobile systems such as smartphones and wearables, edge computing, gaming consoles and automotive. Its fast serial interface and streamlined protocol allow for high data transfer rates leading to strong system performance without draining too much power.
