microSD Card Benchmarks and Reviews

microSD cards are small form factor flash memory that are similar to regular SD cards except they fit into small devices such as smartphones, action cameras and tablets. Additionally, microSD cards can be used in a full-size SD slot by using a microSD to SD card adapter. The cards shown here were benchmarked in several card readers, with the maximum result shown in the table for each.

The benchmark used is CrystalDiskMark version 3.0.3 x64. Settings are 1000 MB, 5 passes, random test data. Benchmarks run with Windows 8.1 Pro and Windows 10 Pro. A list of USB 3.0 card readers used for benchmarks and complete details are available under each review.

When available, a full microSD card review is provided by linking the card name. Reviews show the full read and write speed benchmarks from several card readers in addition to a variety of digital cameras. The reviews here include UHS-I and UHS-II microSD cards. UHS-II microSD cards are backwards compatible and will work in UHS-I mode in SD devices, but only devices that have the UHS-II contacts can take achieve the additional speed of the UHS-II interface.
