128 GB microSDXC card for mobile capture

This Lexar microSDXC card provides 128 GB of storage for smartphones, tablets and action cameras. It is rated UHS-I U1 Class 10 to sustain the write speeds needed for continuous 1080p and 4K video recording. The 633x rating indicates a maximum read speed of 100 MB/s for faster offloading.

UHS-I U1 Class 10 speed rating

The Class 10 and U1 markings guarantee a minimum sequential write speed of 10 MB/s. This is the single specification that determines whether the card can keep up with full HD and 4K video streams without dropped frames. Slower cards without this rating may stall during high-bitrate recording.

Included SD adapter enables desktop use

The bundled SD adapter lets you insert the microSDXC card into full-size SD slots on laptops, card readers or cameras. This removes the need for a separate USB reader when transferring files to a computer. Without the adapter the card only fits microSD slots.
