Samsung introduced industry’s first 256 GB based on Universal Flash Storage ( UFS ) 2.0 technology. Samsung says its performance is similar with the SATA based SSDs used in PCs.
The new UFS memory is not just twice as fast as SATA SSDs, but also supports V-NAND flash memory chips. It can handle 45,000 and 40,000 input/output operations per second (IOPS) for reading and writing. In this case, it is about two times faster than the previous UFS which could handle only 19,000 and 14,000 IOPS.
It has a speed of 850 MB/s reading and 260 MB/s writing. Moreover, it supports 4K movies in split screen mod.
It is expected from Samsung to use this 256 GB Universal Flash Storage on Note 6.
