SD Memory Card Tests

For SD cards, we choose high speed UHS-I memory cards from several major manufacturers. The size chosen is 32GB which is a popular size among photographers. Smaller cards of 8GB and 16GB as well as larger cards 64GB, 128GB and even 256GB are available and tend to perform similarly. We are also testing new UHS-II type cards, however very few cameras currently support the UHS-II standard. In unsupported cameras, the cards perform only at UHS-I speed.

We also test 7 different CompactFlash cards in cameras that still use this older card format. More reviews on these cards will be added soon. For now the results can be seen in the camera test results.

Card Readers

We review memory card readers and test them using a variety of memory carts. You will find that a majority of readers use a USB 3.0 connection capable of 500 MB/s transfer speed. Older USB 2.0 readers have a maximum usable speed of around 35MB/s and can slow down transfers. The USB 3.0 readers are backwards compatible with USB 2.0 devices.
