Overview

The SanDisk 128GB Extreme Pro SD Card Bundle pairs two of SanDisk's professional-grade SDXC memory cards with an Everything But Stromboli multi-format card reader. Each 128GB card is rated for sequential read speeds up to 170MB/s and write speeds up to 90MB/s, making them well suited for rapid burst photography and large file transfers. The UHS Speed Class 3 (U3) and Video Speed Class 30 (V30) certifications guarantee a minimum sustained write speed of 30MB/s, which is the threshold required for recording 4K UHD video without dropped frames.

Having two cards in the bundle gives photographers a practical 256GB of total capacity — enough for extended shoots or a convenient backup rotation where one card stays in the camera while the other is being offloaded. The included combo card reader accepts SD, Micro SD, M2, and Memory Stick formats, streamlining the transfer process without needing to hunt for a dedicated reader. These are standard UHS-I cards compatible with any full-size SD slot that supports SDXC, making them a versatile choice for DSLRs, mirrorless cameras, camcorders, and other devices from Canon, Nikon, Sony, and beyond.
