If Android phones need anything, it's a bit more space; and SanDisk's 400GB microSD card delivers just that.

The new 400GB card, a staggering 144GB bigger than the largest currently on the market, may be the biggest that many people ever need.

The large size makes it perfect for Android smartphones that support the microSDXC standard. Using SanDisk's UHS-I technology, it's also fast enough to deliver video on the go, opening up a world of opportunities.

Where it really comes into its own, however, is when it's used as internal storage. This is a feature of modern Android devices that treats the external SD card as its own memory - for apps, photos and anything else you might like to put on it.
