Samsung Announces UFS 4.0 to Deliver up to 4,200 MB/s Read, 2,800 MB/s Write Speeds for Memory Cards

Samsung has announced the implementation of the latest JEDEC standard specification with the adoption of UFS (Universal Flash Storage) standard 4.0. The new standard offers a number of improvements over the previous UFS 3.1 specification related to either performance or power savings. The new standard increases speeds of up to 23.2 Gbps per lane, double that of the previous UFS 3.1 standard. Additionally, UFS 4.0 unlocks sequential read speeds as high as 6.0 MB/s per mA - a 46% improvement over the previous spec, promising decreased battery drain even as workload time is reduced.

Samsung's UFS 4.0 implementation will leverage the company's 7th Gen V-NAND alongside a proprietary controller, which should ultimately enable speeds of up to 4,200 MB/s. Sequential write speeds are nothing to scoff at either, promising up to 2,800 MB/s. The improved performance doesn't translate to increased package sizes, however, as UFS 4.0 will be distributed in compact packages with a maximum dimension of 11 mm x 13 mm x 1 mm for more effective space utilization and design convenience - with capacities reaching the 1 TB per package. Mass production is expected in 3Q2022. Samsung expects its new UFS 4.0-based products to deliver new experiences with increased data throughput of 5G smartphones, future automotive applications, and even AR and VR.

Up to… My opinion is that it will be very difficult for a mobile device like a phone to sustain this sort of speed due to throttling. All new phones are already struggling to keep the SOC cool, and adding another significant heat source is not going to help.

Well they can advertise water-cooling for their latest flagship phone then :slap:

Just like that 200W hyper time/space bending DART super charge :laugh:

Nice. Thus far flagship parts used either UFS 3.1 that was limited to 512GB or slower UFS 3.0 that had 1TB option. With 1TB UFS 4.0 manufacturers can have the best of both.
