A 400 GB removable memory card for Android and Windows tablets and phones will soon be available from SanDisk, a subsidiary of Western Digital.
This is twice the capacity of what was previously the world’s highest-capacity microSD card, without increasing the size. This was accomplished with design and production processes that allow for more bits per die.
The 400GB SanDisk Ultra microSDXC UHS-I card can hold up to 40 hours of Full HD video. It features transfer speeds of up to 100 MB/s, enabling ushers to move up to 1,200 photos per minute. Additionally, the card meets the A1 App Performance Class specification, which means that the card can load apps faster.
Most Windows and Android tablets have built-in card readers that support the microSDXC standard, but that doesn’t automatically mean all of these computers will be able to access this 400 GB card. WD is breaking new ground, and that always raises the possibility of unexpected problems.
Price and Availability
Cutting-edge storage cards like this always debut at premium prices, and this one is no exception. Western Digital says the 400GB SanDisk Ultra microSDXC UHS-I card will sell for $249.
WD says this product will be sold by SanDisk.com and other retailers, but it isn’t available now. There’s no word on a release date.
