64 GB microSDXC card for phones and tablets

This ADATA Premier microSDXC card delivers 64 GB of storage for smartphones and tablets. It uses the UHS-I interface with a Class 10 speed rating to handle high-definition photos and video recording. The card includes a standard SD adapter for use in larger slots. Error-code correction and resistance to temperature extremes and X-rays protect stored data.

UHS-I U1 speed class for sequential reads up to 50

The single specification that determines suitability is the UHS-I U1 rating, which guarantees a minimum write speed of 10 MB/s and enables sequential reads up to 50 MB/s. This meets the SD 3.0 specification while maintaining backward compatibility with SD 2.0 Class 10 devices. Buyers who need sustained write speeds above 10 MB/s for 4K video or burst photography should consider a higher speed class.

Fits microSDXC slots and full-size SD slots via

The card fits any device with a microSDXC slot and works in full-size SD slots using the supplied adapter. It requires a host that supports the SDXC capacity standard and the UHS-I bus to reach the rated read speed. No external power or driver installation is needed. The durable construction frees users from worry about environmental damage during travel or outdoor shooting.
