Samsung announced the Universal flash storage (UFS) 4.0 so here we bring the comparison between UFS 4.0 vs UFS 3.1, as we know Samsung is the big name when it comes to storage devices and semiconductors. Samsung’s UFS 3.1 is already the biggest performer in the market and now Samsung announce is the next generation of flash storage with huge speed and efficiency gains.
UFS 4.0 vs UFS 3.1 comparison
The new UFS 4.0 offers a speed of up to 23.2Gbps per lane which is 2x faster than the UFS 3.1 and this bandwidth is perfect for the 5G smartphones for faster data processing, in the future, it should be adopted by the automotive applications.
It comes with Samsung advanced 7th generation V-NAND that delivers a sequential read speed of up to 4200MB/s and Sequential write speed of up to 2800MB/s whereas UFS 3.1 comes with 2100MB/s read speed and 1200MB/s write speed
Power efficiency has also improved by 46% compared to UFS 3.1, it can deliver a sequential read speed of 6MB/s per mA so users can get more battery life with speedy performance.
The All-new UFS 4.0 will come in a compact package with a maximum size of 11mm x 13mm x 1mm which is slightly less compact than UFS 3.1 (11.5mm x 13mm x 1mm).
