Sandisk announces faster 400GB micro-SD card – predecessor drops in price

Sandisk has announced a new 400GB micro-SD card that should be able to achieve maximum sequential reads of 160MB/s. That is far more than the 400GB micro-SD card Sandisk announced last summer, this card was able to achieve maximum sequential reads of up to 100MB/s.

The 400GB SanDisk Extreme UHS-I microSD card is UHS-I U3 certified, and also has an A2 indication which means the card should be able to achieve random reads of 4,000 IOPs and random reads of 2,000 IOPS. The latter should make sure that apps, installed on the SD card, load faster. Sequential reads are specified at a maximum of 90 MB/s.

Sandisk is able to cram so much capacity in the small microSD form-factor because it uses 3D NAND.

Together with the release of the 400GB SanDisk Extreme card, the price of its predecessor, the 400GB SanDisk Ultra card, dropped severely. It’s currently available on Amazon at $189.99, the lowest price ever.
