Western Digital Corporation, a global data storage technology and solutions leader, today announced its 400 GB SanDisk Ultra microSDXC UHS-I card, the world's highest-capacity microSD card for use in mobile devices. Two years after introducing its record-breaking 200 GB SanDisk Ultra microSDXC card, Western Digital has doubled the capacity within the same tiny form factor. Keeping up with the demands of today's mobile-centric lifestyle, the new SanDisk microSD card provides consumers with the freedom to capture, save and share photos, videos and apps, and enjoy offline content - all without worrying about storage limitations.

"Mobile devices have become the epicenter of our lives, and consumers are now accustomed to using their smartphones for anything from entertainment to business. We are collecting and sharing massive amounts of data on smartphones, drones, tablets, PCs, laptops and more. We anticipate that storage needs will only continue to grow as people continue to expect more sophisticated features on their devices and desire higher quality content," Jeff Janukowicz, research vice president, IDC. "We estimate mobile device users worldwide will install over 150 billion applications alone this year, which require a ton of memory on all of our favorite devices."



Western Digital achieved this capacity breakthrough by leveraging its proprietary memory technology and design and production processes that allow for more bits per die. "We continue to push technology boundaries and transform the way consumers use their mobile devices," said Sven Rathjen, vice president, product marketing, Western Digital. "By focusing on achieving new technology milestones, we enable consumers to keep up with their mobile-centric lifestyles with storage solutions they trust."

Ideal for Android smartphone and tablet users, the world's highest-capacity card can hold up to 40 hours of Full HD video and features superfast transfer speeds of up to 100 MB/s to deliver premium performance. At this transfer speed, consumers can expect to move up to 1,200 photos per minute. Additionally, the 400 GB SanDisk Ultra microSD card meets the A1 App Performance Class specification, which means that the card can load apps faster.

Through the updated SanDisk Memory Zone app, users will have even greater control over their mobile device's memory storage. The app, available for free download from the Google Play store, is compatible with most Android-powered devices and allows users to easily locate, organize, transfer and back up data, including tagged content from Facebook and Instagram.

Pricing and Availability
The ground-breaking 400 GB SanDisk Ultra microSDXC UHS-I card features a ten-year limited warranty and will be available at SanDisk.com and other major retailers at a U.S. manufacturer's suggested retail price (MSRP) of $249.99.

Performance seems to be very crappy compared to, let's say, Lexar's cards:
https://www.amazon.com/dp/B012PKPU5W/?tag=tec06d-20

It's fast enough to stream raw UHD BR, so it's fine for most people buying it to add 400GB to their phone, which is the primary market for it.

Faster UHS-II cards are loved by photography peeps, but they don't really have a problem with swapping cards around as one fills up for the most part.

How is that insane density possible with these but not with SSDs?

Consumer demand.

You can get really dense SSDs easily (Samsung recently announced a 128TB 15mm thick 2.5" SSD to replace their almost 2 year old 15.36TB 15mm thick 2.5" SSD) if you're willing to pay server-level monies.

The SSD's have infact a problem with density, less chips means less parallelism & lower (max) speeds.
This is why you're seeing 128GB capacities being phased out with 3D TLC, we'll probably be seeing 256GB become rarer as 3D TLC gets more dense.

Lexar brand is dead now though, so get their products now before they are all out.
Just for the sake of competition let's hope someone will pick-up Lexar. That whole decision by Micron came as a shock for me as Lexar and Sandisk were the only manufacturers from whom I purchased memory cards.

Aye, however, are there any devices out there that can support more than 256GB MicroSD cards??

2 x 128TB SSDs in RAID 1 yes please.

You can't get as dense, and still maintain an SSD's performance level. It would have a thermal meltdown.
