At Mobile World Congress, Western Digital is showcasing the world’s fastest 1TB UHS-I microSD flash memory card, the 1TB SanDisk Extreme UHS-I microSDXC card.

The new card features higher speed and capacity for capturing and moving massive amounts of photos and videos on smartphones, drones and action cameras.

The 1TB SanDisk Extreme UHS-I microSD card reaches speeds up to 160MB/s and write speeds of up to 90MB/s, much like the 400GB one Western Digital launched last year. This new card allows consumers to transfer files in nearly half the time over standard UHS-I microSD cards currently on the market. The cards reach these speeds by leveraging Western Digital’s flash technology. The casr also uses the SD Association's A2 specification to get apps launched quickly.

The new SanDisk Extreme card will also be available in 512GB capacity, and will feature the A2 specification for launching and loading apps fast.

The 1TB and 512GB SanDisk Extreme UHS-I microSD cards are available for pre-order now on SanDisk.com, and will be available at select retailers in April 2019. The cards will be priced at U.S. MSRPs of $449.99 and $199.99, respectively.

Micron also announced its own 1TB microSD card. The Micron c200 1TB microSDXC UHS-I card is a bit slower4 than WD's offering, capable of reading speeds of up to 100 MB/s and write speeds of up to 95 MB/s. But it is also Application Performance Class 2 (A2) certified for smooth running of applications if you choose to use your apps from the external storage. Pricing of the Micron c200 1TB microSDXC card is yet to be announced.
