The world’s largest microSD card – SanDisk Ultra 400GB

Western Digital has launched the world’s highest-capacity microSD card, the SanDisk Ultra microSDXC UHS-I 400GB.

The card comes two years after the company launched the 200GB SanDisk Ultra microSDXC card.

Western Digital said it achieved the “capacity breakthrough” by leveraging its proprietary memory technology – allowing for more bits per die.

The 400GB card features transfer speeds of up to 100MB/s, and it meets the A1 App Performance Class specification – letting users load apps faster.

The card features a 10-year limited warranty and will sell for $249.99.
