Samsung microSD cards hit UHS-1 speeds
Samsung's memory cards were updated late Wednesday with large-scale production one of the world's fastest microSD cards. The new 16GB microSDHC card runs at the same UHS-1 (Ultra High Speed-1) spec normally used for the latest full-size SD cards, giving it performance that would previously have been reserved for pro memory for DSLRs and video cameras. Sequential read speeds peak at about 80MB per second, or roughly four times the 21MB of regular microSD cards.
The storage is ostensibly meant for LTE-capable smartphones and tablets, where flash memory speed could bottleneck the connection. It should nonetheless be useful for cameras that take microSD storage and support UHS-1. Samsung reached the density through a combination of its more recent 20-nanometer manufacturing process to build 64-gigabit (8GB) chip layers as well as a toggle DDR2 interface that can saturate the newly available bandwidth.
Release schedules and prices weren't given out, although mass production usually precedes a launch within a few months or less.
