Tech giant to introduce 256GB chips for smartphones

"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" said Samsung.

"In terms of sequential writing, it supports up to 260MB/s, which is approximately three times faster than high-performance external micro SD cards."

Samsung said the new chips will allow users to store 4K motion pictures, and exchange information faster over gadgets that use USB 3.0.
