Western Digital has announced two new SanDisk memory products: the SanDisk iXpand Base for iPhone backup and charging, and the industry’s highest capacity microSD card for use in mobile devices, the 400GB SanDisk Ultra microSDXC UHS-I. Both of these products are available today.

The iXpand comes in capacities of 32GB through 256GB, giving users a viable alternative to paying monthly fees for cloud-based storage. It sports a compact form factor design so it can sit on a desk without it taking up too much space. Additionally, its soft rubber top allows phones to be set securely in place and features a nice wrap-around groove to keep a Lighting cable out of the way. You can also complete charges very quickly via its 15W charging power.

Using the iXpand Base is simple: just plug the device into a phone, and it will automatically back up user content via the iOS app (while charging at the same time). Restoring backed up content is just as easy. Once in the app, simply tap restore to transfer files back to the iPhone.
