At Mobile World Congress SanDisk has announced the world’s fastest UHS-I flash memory card, the 400GB SanDisk Extreme A2 UHS-I microSDXC card. This 400GB card is the same physical size and capacity as the original card, but is more than 50 percent faster!
The speed increase is thanks to the proprietary PCI-e technology from Western Digital, which is its parent company. The card is able to achieve read speeds of up to 160 MB/s and write speeds of up to 90 MB/s.
The speed and capacity of this card make it great for people who are shooting 4K video and photographers who are shooting lots of RAW photos.
