Samsung Electronics has started mass producing a microSD card that uses an Ultra High Speed-1 (UHS-1) interface to improve data transfer speeds in LTE smartphones and tablets.

The microSD HC card stores up to 16GB and has a maximum sequential read speed of 80MBps (megabytes per second), according to internal tests conducted by Samsung. That is more than four times the read speed of today's advanced microSD cards, which have speeds up to 21MBps, Samsung said.

What real-world speeds that will translate into remains to be seen, although Samsung said that the card will be a good fit for LTE smartphones and tablets.

Cards that can store more than 16GB and offer the same are speeds on the way, according to Samsung.

Samsung didn't say when the card will start shipping or what it will cost.
