Sandisk's super-fast 400GB microSD is ready for 4K HDR video
It's great that Sony's new Xperia XZ2 smartphone can record 4K HDR video footage, but the bandwidth and storage requirements are bound to be, er, extreme. That's where SanDisk's new 400GB Extreme UHS-I microSDXC card comes in, delivering 160 MB/s read and 90 MB/s write speeds while maintaining compatibility with most devices. It also conforms to the A2 specification (4000 IOPS read and 2000 IPS write), meaning it'll let you launch apps more quickly.
