Western Digital today announced a 400GB SanDisk Ultra microSD which it claims is the world’s highest-capacity microSD card.

Priced at $249.99, the 400GB microSD card should theoretically work with all major flagship Android devices which feature a microSD card. Western Digital-owned SanDisk had previously launched a 256GB microSD card earlier in the year which was the world’s highest-capacity card all this while. The card features transfer speeds of up to 100MB/s and can store Full HD videos of up to 40 hours. The card has an A1 rating which as per SanDisk will ensure optimum app loading times. With smartphones now featuring QHD+ displays and being able to record 4K videos easily, the need for local storage from users will continue expanding. While SanDisk’s 400GB microSD card is likely going to find only a few takers, it will help push down the price of other lower storage cards which would ultimately benefit end consumers. The 400GB SanDisk Ultra card goes on sale starting today for $249.99.
