“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 market,” says Samsung executive vice-president Joo Sun Choi. “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 256GB memory is made on Samsung’s V-NAND process with a controller. The UFS memory handles up to 45,000 and 40,000 input/output operations per second (IOPS) for random reading and writing respectively, over two times faster than the 19,000 and 14,000 IOPS of the previous generation of UFS memory.
For sequential reading, the 256GB UFS takes advantage of two lanes of data transfer to move data at up to 850MB/s, which is nearly twice as fast as a typical SATA-based SSD used in PCs. In terms of sequential writing, it supports up to 260MB/s, which is about three times faster than high-performance external micro SD cards, according to Samsung.
As a result, the new 256GB UFS memory is capable of supporting Ultra HD video playback and multitasking functionality on large-screen mobile devices, such as watching 4K Ultra HD movies on a split screen, while searching image files or downloading video clips.
The USB 3.0 interface transfers a 5GB-equivalent Full-HD video clip (average 90-min. movie size) in 12 seconds.
