Overview

The SanDisk SDSQUAB-064G-GN6MT Ultra microSDXC two-pack delivers a pair of 64GB memory cards built on SanDisk's proven Ultra platform. Each card offers read speeds up to 140MB/s thanks to SanDisk's proprietary technology that pushes beyond the standard UHS-I 104MB/s specification, translating to the ability to transfer roughly 1,000 photos per minute when used with a USB 3.0 card reader. The A1 Application Performance rating ensures that apps stored and run from the card on Android devices launch and operate smoothly, meeting minimum thresholds of 1,500 read and 500 write IOPS.

With Class 10 and UHS-I speed class ratings, both cards are well-suited for capturing Full HD 1080p video and high-resolution photos on smartphones, tablets, action cameras, and drones. The two-pack format is practical for households with multiple devices, for keeping a spare on hand, or for swapping between devices without needing to transfer files. Each card provides 64GB of usable storage, giving you a combined 128GB across the pair for photos, video, music, and app data.
