Samsung Electronics has officially started mass production of industry's first 256 GB memory chip based on the Universal Flash Storage 2.0 (UFS) standard. The company boasts the new chip features outstanding performance for mobile devices, which exceeds that of a typical SATA-based SSD for PCs. In fact, data transfer is up to 850MB/s read and 260MB/s write. That's three times faster than high-performance micro SD cards. The chip, which is based on the company's V-NAND tech, boasts up to 45,000 read and 40,000 write operations per second. (IOPS). That's two times faster than the previous gen UFS memory. As you can guess, watching and recording 4K movies is a breeze for the chip. Samsung also hints at its future phones supporting USB 3.0 interface and says with this new 256GB UFS 2.0 chip, transferring a 90-minute 1080p video will take just 12 seconds. The Samsung Galaxy Note 6 will quite probably come out this September and it doesn't sound outlandish that the company's flagship phablet will be the first phone to feature such storage...
