64GB microSDXC UHS-I card

This 64GB Lexar microSDXC card uses UHS-I technology to reach read speeds up to 95MB/s (633x) and meets Class 10 performance. It is built for sports camcorders, tablets and smartphones that need quick capture and playback of 1080p full-HD, 3D and 4K video files. The card includes an SD adapter for wider device compatibility.

Class 10 rating with SD adapter

The UHS-I interface delivers up to 95MB/s read transfer on compatible hosts while the Class 10 rating ensures reliable performance on non-UHS devices. An included SD adapter lets you move files to laptops or readers that only accept full-size SD cards, simplifying everyday workflows. All units pass extensive testing in Lexar Quality Labs across more than 1,200 digital devices.

Low power solid-state storage

With no moving parts the card draws minimal power and runs silently, helping battery life in cameras, tablets and phones. Solid-state construction resists shock and vibration during active use, and the 64GB capacity holds hours of HD video or thousands of photos without needing frequent offloads. Buyers who need more than 64GB should consider the 256GB model in the same series.
