[PConline News] Smartphones have come a long way, not only in terms of storage capacity but also in speed and performance. The latest UFS standards are now matching up with SSD drives, making them the go-to choice for high-end smartphones. Toshiba has recently announced the launch of its next-generation UFS 2.1 flash memory, built on the cutting-edge 64-layer BiCS 3 flash technology. This new generation offers capacities ranging from 32GB to 256GB, comes in BGA packages, and delivers read speeds of up to 900MB/s—representing a 200% improvement in random read performance compared to previous versions.
Currently, UFS 2.1 flash memory is mainly supplied by Samsung and Toshiba for smartphones on the market. While Samsung holds the largest market share, it's mostly used in its own devices. Even then, they still need to source some UFS 2.1 chips from Toshiba, as seen in the Galaxy S8 series. Toshiba has previously released several UFS 2.1 products, but this time, the technology has been significantly upgraded with the use of 64-layer BiCS 3 flash memory, resulting in better performance and lower power consumption than before.
The new UFS 2.1 from Toshiba starts at 32GB, with options up to 256GB. It integrates both the controller and flash memory into a single package and supports the JEDEC standard 11.5x13mm form factor. In terms of speed, it supports the HS-Gear3 standard, offering 5.8 Gbps per channel, with dual channels reaching up to 11.6 Gbps. For example, the 64GB version can read at 900MB/s and write at 180MB/s. Random performance has seen massive improvements—random reads have increased by 200%, and random writes by 185%, nearly doubling the performance of the previous generation.
This advancement makes UFS 2.1 a major leap forward in mobile storage, offering faster data access and improved efficiency, which is especially important for high-performance smartphones that demand quick response times and smooth multitasking. As more manufacturers adopt this technology, we can expect even better user experiences in future flagship devices.
