Samsung begins mass production of fast storage

eUFS 3.1

Samsung Electronics has begun mass producing the industry’s first 512-gigabyte (GB) eUFS (embedded Universal Flash Storage) 3.1 for use in flagship smartphones. Delivering three times the write speed of the previous 512GB eUFS 3.0 mobile memory, Samsung’s new eUFS 3.1 breaks the 1GB/s performance threshold in smartphone storage.

“With our introduction of the fastest mobile storage, smartphone users will no longer have to worry about the bottleneck they face with conventional storage cards,” said Cheol Choi, executive vice president of Memory Sales & Marketing at Samsung Electronics. “The new eUFS 3.1 reflects our continuing commitment to supporting the rapidly increasing demands from global smartphone makers this year.”

At a sequential write speed of over 1,200MB/s, Samsung 512GB eUFS 3.1 boasts more than twice the speed of a SATA-based PC (540MB/s) and over ten times the speed of a UHS-I microSD card (90MB/s). This means consumers can enjoy the speed of an ultra-slim notebook when storing massive files like 8K videos or several hundred large-size photos in their smartphones, without any buffering. In terms of random performance, the 512GB eUFS 3.1 processes up to 60 percent faster than the widely used UFS 3.0 version, offering 100,000 input/output operations per second (IOPS) for reads and 70,000 IOPS for writes.

Along with the 512GB option, Samsung will also have 256GB and 128GB capacities available for flagship smartphones.
