With phones like Galaxy S II that can capture video at 1080p resolution it is important for the device to transmit data to the storage without any issues. This is why, Samsung has introduced new 20nm-class microSD cards with a speed rating of class 10.
The new 32GB microSD cards integrate 32Gb 3-bit NAND flash memory chips and a proprietary 3-bit NAND controller that helps to deliver high speeds like write speed at up to 12MB/s and read speed at 24MB/s. In comparison, the new card’s speed is more than double the speed of class 4 microSD cards.
