64GB microSDXC U3 Class 10 card

This SanDisk Extreme Pro microSDXC card provides 64GB of storage for devices that accept the microSD form factor. It carries a Class 10 UHS-I U3 speed rating and is suited for recording 4K video or capturing high-resolution photos. The card is sold new and includes a standard SD adapter for use in full-size slots.

UHS-I U3 interface with OTG reader bundle

The card operates over the UHS-I bus and delivers sequential read speeds up to 95MB/s and write speeds up to 90MB/s. An OEM microUSB OTG USB 2.0 card reader is included, allowing direct connection to smartphones or tablets that support USB On-The-Go functionality. This bundle frees up the need for a separate adapter when transferring files between the card and mobile devices.

For 4K capture on UHS-I devices.

This card suits photographers and videographers who need sustained write performance for 4K recording on cameras, drones or action cams that support UHS-I U3. It also fits mobile users wanting to expand storage on microSD-equipped phones or tablets. Buyers requiring the faster throughput of UHS-II or UHS-III bus interfaces, or those needing capacities beyond 64GB, should look at other options.
