In camera testing the Patriot EP Pro 32GB had mixed results. It performed consistenly in the Nikon D750, measuring 39 MB/s continuous write speed. However in our Canon 7D Mark II test it fared much worse, averaging only 10MB/s write speed. Several attempts to reformat the card including a zero-fill format did not remedy its poor performance and at one point the card managed only 5 to 6 MB/s write speed over a series of runs. It also had mixed performance in the Canon T6i and T6s. It did function properly in all our card readers and other cameras, so we suspect a compatibility issue between this particular card and certain Canon cameras.
