SanDisk this week introduced the 400GB Ultra microSDXC UHS-I card, which is not only the world's highest capacity microSD card but one from which smartphones, tablets or laptops can run applications.

According to SanDisk, the micro SDcard achieves UHS Speed Class 1 – the best performance available for a microSD card and one that enables the speedy loading and running of apps.

"What this means for users is that, in theory, they will no longer be limited to only having apps on the main memory in the device," said Jack Gold, principal analyst with J. Gold Associates.

This is pretty much equivalent to putting a USB drive on your computer and running apps from that."
