These are the Fuji Professional 100x compact flash cards with a write speed of up to 15Mb per second depending on device. We find these extremely reliable and have not had a Fuji card returned in over five years that we have been supplying them to the professional trade. Because of that, they are almost the only brand of cards we now sell.

Being from the Professional Series, they are covered by a lifetime guarantee.
