I could have sworn that SanDisk made 256GB MicroSDXC cards already, but it seems like it didn't. It just announced them though, so I'm not awfully wrong anymore. There are two new cards in SanDisk's portfolio of super duper ultra high capacity: the SanDisk Extreme MicroSDXC UHS-I and SanDisk Ultra MicroSDXC UHS-I card, Premium Edition.

I know that sounds confusing so I will break it down to you. Both of these cards can hold 256GB of storage and both are Class 10 cards for great Full HD video capture. They're both super fast too, and very resilient to shock, water, temperature changes, and X-rays, but the difference lies in one aspect. The Extreme card is also rated UHS Speed Class 3, which means that it can easily save 4K Ultra HD video. It's also slightly faster with transfer speeds up to 100MB/s compared to 95MB/s on the Ultra card. SanDisk's press release positions the Extreme card for action cameras, powerful drones, and 4K-capable smartphones, and the Ultra card for Android smartphone and tablet users who don't want to run out of space.

The 256GB SanDisk Extreme card will be released in Q4 2016 with an MSRP of $199.99, whereas the Ultra card will be available in August with an MSRP of $149.99. I can't wait for these to start showing up at around $50 in our deal alert posts, maybe in a year or so.
