Samsung announced the industry's first 256GB embedded memory based on the Universal Flash Storage (UFS) 2.0 standard, which is meant to replace the eMMC standard. Samsung says that its new UFS 2.0 drive is faster even than some SATA-based SSDs for PCs.
"By providing high-density UFS memory that is nearly twice as fast as a SATA SSD for PCs, we will contribute to a paradigm shift within the mobile data storage marketup to 45,000 and 40,000 input/output operations per second (IOPS) for random reading and writing respectively," said Joo Sun Choi, Executive Vice President, Memory Sales and Marketing for Samsung Electronics. "We are determined to push the competitive edge in premium storage line-ups – OEM NVMe SSDs, external SSDs, and UFS – by moving aggressively to enhance performance and capacity in all three markets."
The new embedded storage module is based on Samsung's own V-NAND technology and comes with a "specially-designed high-performance controller." The latest UFS 2.0 memory supports up to 45,000 and 40,000 input/output operations per second (IOPS) for random reading and writing, respectively. That is twice as fast as the previous UFS generation that supported 19,000 and 14,000 IOPS for random read and write workloads.
Samsung's 256GB module achieves up to 850MB/s sequential read speed, which is twice as fast as many SATA SSDs. It also supports up to 256MB/s sequential write speed, which Samsung says is three times faster than what high-performance microSD cards can currently achieve.
These speeds should be more than fast enough to support 4k video playback, and the 256GB memory allows for storage of up to 47 Full HD movies, according to Samsung. The company also said that next-generation smartphones should support USB 3.0 speeds, which means you'll be able to transfer those large files much more quickly to your device as well.
Samsung had already announced the 128GB UFS 2.0 storage module a year ago, and since then the company managed to both double the capacity and the performance of the new 256GB module thanks to its V-NAND technology. The new storage chip should be available in products by the end of the year.
