512GB eUFS 3.0

Samsung today announced that it has begun mass production of its Fastest 512GB eUFS 3.1 Flash Storage for Flagship Smartphones. The production will include the industry’s first 512GB (gigabyte) eUFS 3.1 (embedded Universal Flash Storage) for use in flagship smartphones. The new flash storage drive will deliver three times faster than the write speed of the previous 512GB eUFS 3.0 mobile memory. The new eUFS 3.1 flash storage will break 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.”

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. User will be able to transfer and store massive files like 8K videos or thousands of large-size photos in their smartphones, without any buffering.


Samsung also revealed that transferring data between two phones over the new eUFS 3.1 will only take about 1.5 minutes to move 100GB of data whereas UFS 3.0-based phones require more than four minutes.

Along with the 512GB option, there will also be a 256GB and 128GB storage options available for flagship smartphones.
