A Do-It-Yourself CFexpress Type B Memory Card

Once considered an exotic choice, CFexpress Type B memory cards have become the gold standard in recent years. While they’re still not as common as the mass-adopted SD cards, many high-end cameras now feature at least one CFexpress slot, including from Canon, Nikon, Leica, Fujifilm, and Hasselblad. The reason is simple: these cards offer excellent speed for the demanding professional photographer.
