Camera Memory Speed
Memory Card Comparison & Performance Tests for Digital Cameras

Secure Digital Memory Cards

This page contains a table of SD card benchmarks for all cards tested. Those cards with extended reviews are linked by the card name. The benchmark tests were performed in several card readers, with the highest result shown for each individual benchmark. Cards tested include SDHC and SDXC cards. The SD cards range in capacity from 16GB to 256GB. Both UHS-I and UHS-II cards are tested. UHS-II cards are backwards compatible and will work in UHS-I mode in SD devices, however only devices that support UHS-II can take advantage of the additional speed provided by UHS-II cards.
