Around two years after releasing its 200 GB microSD card, the world's highest-capacity at the time, SanDisk has today doubled that figure to unveil a whopping 400 GB version, again the world's highest.

SanDisk is working hard to keep pace with the demands of today's data-heavy mobile user. The 200 GB microSD card came just one year after the company turned up to Mobile World Congress in 2014 with a record-breaking 128 GB microSDXC card.

So as we can see, things are progressing pretty quickly when it comes to micro mobile storage. In an era where people are capturing and sharing more and more photos and video on smartphones, as well as other microSD-capable devices like drones and action cams, SanDisk is having a pretty big hand in moving things along.

It claims its new 400 GB microSD can hold up to 40 hours of full HD video with transfer speeds of up to 100 MB per second, allowing users to move 1,200 photos per minute. It also promises faster app-loading, with the card meeting the A1 App Performance Class specification.

SanDisk's 400 GB microSD card will be priced at US$250, though the company hasn't detailed when exactly it will become available.
