The new Ultra Capacity (UC) designation will mean capacities of up to 128 terabytes and the “Express” designation will mean transfer speeds of up to 985 megabytes per second.
SO now you can store almost every peace of data in a single SD CARD.
With the evolving technology, the smartphones video games and IOT devices are capable of doing more things, 360 degree photos and videos Virtual Reality ultra-high resolution content video Streaming we needs faster and reliable storage .
