SanDisk has a new record-breaking microSD coming to market, which will deliver so much storage you might be at a loss as to what to do with it all. The new 400GB SanDisk Ultra microSDXC UHS-I card is the world’s highest capacity card of its type, and is ideally suited for use in Android smartphones that feature an expansion slot.

Android’s most recent versions allow you to adopt microSD-based storage as “native internal” storage, which allows you to use it to install apps, store photos and more as if you were using a built-in flash memory drive. Most recent Android devices that offer a microSD slot will support the new 400GB chip out of the box, meaning you can get your phone up to almost double what the top-end iPhone currently offers in onboard storage.
