MicroSD cards are handy because you can use them in phones, tablets, game consoles, and lots of other devices, and today Amazon is offering a nice deal on one of the largest microSD cards available.

The 400GB SanDisk microSD card is now on sale at Amazon. This price is significantly lower than the one that this 400GB microSD card launched at last year, so if you're interested in adding nearly half a gigabyte of storage to your mobile device, this is a deal to consider.

SanDisk's microSD card is Class 10 and offers transfer speeds of up to 100MB/s. It's also A1-rated, which SanDisk says will help to load apps more quickly.

Also of note is that this microSD card comes with a full-size SD adapter.

There's no word on how long the sale on this 400GB SanDisk microSD card will last, so if you're on the fence, you may want to act soon.
