Overview

The SanDisk SDSDXEP-064G-GN4IN 64GB Extreme PRO UHS-II SD card is built for prosumers and professionals who demand consistent, high-speed performance from their memory cards. With read speeds reaching up to 280MB/s, transferring large files from card to computer is remarkably quick — a significant time saver during post-production workflows. The 100MB/s write speed, backed by a V60 Video Speed Class rating, ensures smooth, uninterrupted recording of 6K and 4K UHD video on compatible MIL and cinema cameras, as well as reliable continuous burst mode and time-lapse capture.

Durability is a standout feature of this card. SanDisk has engineered it to be waterproof, temperature proof, x-ray proof, magnetic proof, and drop proof, making it a dependable choice for outdoor and on-location shoots where gear faces the elements. At just 1.67 grams and standard SDXC dimensions (0.94" x 1.26" x 0.09"), it fits any full-size SD slot. While the 64GB capacity is well-suited for shorter projects or as a backup card, professionals shooting extended high-bitrate footage may want to consider larger capacities in the same Extreme PRO line for longer sessions without swapping cards.
