The company Samsung has today announced that they are starting to manufacture a new high performance MicroSD card, which has twice the data transfer speed compared to its previous generation of MicroSD cards designed for smartphones.
This new MicroSD card can hold up to 32GB of data and has a read data transfer speed of up to 24MB/Sec and writes up to 12MB/Sec.
That’s more than the double of the maximum write speeds of the Class-4 32GB MicroSD card generation.
Samsung’s new MicroSD card is based on their 20nm NAND flash memory chips instead of the previously chips, which were made in a 30nm process. According to Samsung this transition has made the productivity of the chips over 30% better.
The reason that Samsung are starting to make these is because of the smartphone industry has a demand for new high performance MicroSD cards for the next generation of mobile application and for 4G models of smartphones.
Just a quick note about SD card classes.
There are Class 2, 4, 6 and 10.
Class 2, 4 and 6 are mainly used for normal speed units, for an example a normal Video Recorder, where a Class 10 is used for a High-Definition Video Recorder.
Just to put it a bit in perspective J
