Manages properly with this card. Have 3 identical cards and can not complain about the speed during recording yourself (with Canon EOS 60D) or when reading. Do not be speed tests done, like other reviewers here, but I consider the processing speed for absolutely sufficient for the private user (pictures, partly in RAW, up to 5000 individual images in a download process).
Very reliable map, as actually always SanDisk. Can only recommend a purchase. *****
