SanDisk Extreme 64GB microSDXC Card

The SanDisk Extreme microSDXC card offers 64GB of storage for action cameras, drones and Android smartphones. It delivers read speeds up to 170MB/s and write speeds up to 80MB/s using UHS-I Class 10, U3, V30 and A2 ratings. The card supports 4K UHD and Full HD video recording without dropped frames. A full-size SD adapter is included for broader device compatibility.

Ideal for action cameras and mobile app performance

This card suits creators capturing 4K UHD footage or burst photography who need sustained write performance of 80MB/s. The A2 rating accelerates app loading on compatible smartphones. Buyers needing sustained write speeds above 80MB/s or capacities beyond 64GB for extended 4K sessions should consider higher-capacity or faster-tier options. Devices limited to UHS-I speeds will not benefit from UHS-II readers.

UHS-I V30 speed class for 4K video

The V30 speed class guarantees a minimum sustained write speed of 30MB/s, which is the specification that determines reliable 4K UHD recording. Maximum read performance of 170MB/s requires the SanDisk Professional PRO-READER to achieve stated rates. Without a compatible reader, transfer speeds will be lower. The 64GB capacity holds approximately two hours of 4K footage depending on bitrate.

Perguntas sobre este artigo

Should I choose the 64GB version or a larger capacity for faster speeds?

The 64GB card delivers read speeds up to 170MB/s and write speeds up to 80MB/s. Higher read and write figures of 190MB/s and 130MB/s apply only to the 256GB to 1TB capacities.

What does the 170MB/s read speed mean when I use the card in my camera or phone?

You can offload 4K UHD footage and high-resolution photos to a computer quickly when paired with the SanDisk Professional PRO-READER, achieving the stated maximum read performance.

How does the UHS-I interface affect the card's real-world performance ceiling?

The UHS-I bus caps the maximum transfer rate, so the card's 170MB/s read and 80MB/s write ratings represent the practical limits you will see with compatible devices and readers.
