400GB SanDisk Ultra microSDXC UHS-I card – World’s Highest-Capacity microSD Card

Western Digital Corporation’s 400GB* SanDisk Ultra® microSDXC™ UHS-I card, the world’s highest-capacity microSD card for use in mobile devices. Two years after introducing its record-breaking 200GB* SanDisk Ultra microSDXC card, Western Digital has doubled the capacity within the same tiny form factor. Keeping up with the demands of today’s mobile-centric lifestyle, the new SanDisk microSD card provides consumers with the freedom to capture, save and share photos, videos and apps, and enjoy offline content – all without worrying about storage limitations.

Western Digital achieved this capacity breakthrough by leveraging its proprietary memory technology and design and production processes that allow for more bits per die.

“We continue to push technology boundaries and transform the way consumers use their mobile devices,” said Sven Rathjen, vice president, product marketing, Western Digital. “By focusing on achieving new technology milestones, we enable consumers to keep up with their mobile-centric lifestyles with storage solutions they trust.”

Ideal for Android™ smartphone and tablet users, the world’s highest-capacity card can hold up to 40 hours of Full HD video and features superfast transfer speeds of up to 100MB/s** to deliver premium performance. At this transfer speed, consumers can expect to move up to 1,200 photos per minute1. Additionally, the 400GB* SanDisk Ultra microSD card meets the A1 App Performance Class specification, which means that the card can load apps faster.2

Through the updated SanDisk Memory Zone app, users will have even greater control over their mobile device’s memory storage. The app, available for free download from the Google Play™ store, is compatible with most Android-powered devices and allows users to easily locate, organize, transfer and back up data, including tagged content from Facebook and Instagram.3
