ProGrade Digital makes a wide range of memory cards, targeting their products at the professional market. While their Iridium line of CFexpress Type A cards have already shown fantastic performance in my hands-on review, the combination of their blazing speed and larger capacities left them with a higher MSRP (although still at a good price per GB, to be clear). With the Gold line, ProGrade is bringing many of the desirable features to a lower pricepoint and capacity.
