WD Reveals New microSD Cards & New NVMe SSDs At MWC

Today at the Mobile World Congress (MWC) 2018, Western Digital revealed new mobile and computing solutions aimed at maximizing performance. These products include the 400GB SanDisk Extreme UHS-I microSDXCT card (that WD is calling the world’s fastest UHS-I memory card) and new NVMe SSDs with a new NVMe storage architecture. WD will be demoing their new PCIe-enabled SD Card as well.

Mobile capacity needs are increasing along with the need for the mobile storage to perform faster. Technologies like virtual reality, augmented reality, and 4K video (on both smart mobile devices as well as drones) are just some of the drivers behind this need. To meet these customers needs, WD introduced the 400GB SanDisk Extreme UHS-I microSDXCT card. WD claims that the new card can hit speeds of 160MB/s and features the A2 specification.

On the SSD front, customers have similar needs centering around performance and capacity both for computing and for IoT. WD is introducing two new NVMe M.2 SSDs that are powered by new storage architecture that it states is scalable for implementations such as IoT, edge computing, and mobile computing systems. The drives come with new firmware and controller architecture geared toward performance and scalability benefits. The drives include the edge performance PC SN720 with capacities of 2TB and performances of 3.4GB/s read and 2.8GB/s write and the PC SN520 aimed at IoT with capacity of 512GB and smaller M.2 form factors.
