A Deep Dive into Memory Cards: Speed, Maintenance, Formatting and More
Memory cards might be one of the least exciting things in your camera bag…right up until one fails, or a camera buffer "locks up" in the middle of an incredible wildlife moment, or you find your card simply isn't fast enough. In this episode, Court does a deep dive into how memory cards actually work, what all those increasingly cryptic symbols on the front mean, and—more importantly—how to choose the right card for the way you photograph. The episode covers SD vs. CFexpress, read speed vs. write speed, UHS-I vs. UHS-II, V30/V60/V90 ratings, card capacity, camera buffers, dual-card setups, formatting, backups, field care, and a whole lot more. At the end of the day, the best memory card is the one a photographer almost never has to think about. Court's advice is to choose something that matches the camera and the way it's being used, build a solid backup and formatting routine around it, take care of it in the field, and then get back to worrying about the much more interesting stuff happening on the other side of the lens. A Quick Memory Card Cheat Sheet General photography / landscapes / casual travel: A good-quality SD card is usually plenty. If the camera supports UHS-II, it's worth considering, but there isn't necessarily a need for the fastest card available. Wildlife, birds, and action: Write speed becomes much more important. When shooting large RAW files at 15, 20, or 30+ frames per second, a slow card can become a bottleneck very quickly. High-resolution cameras: The bigger the files and the faster they're being captured, the more card speed matters. Video: Pay particular attention to sustained write speed . This is where V30, V60, and V90 ratings become important. Photographers should always check their camera's requirements for the specific video mode they're using. CFexpress: If a camera supports it and you're routinely shooting large RAW bursts, high-frame-rate wildlife, 4K/8K video, or RAW video, CFexpress can be a major performance upgrade. Capacity: For many still photographers, Court thinks 128GB–256GB is a great sweet spot. High-megapixel wildlife shooters and hybrid photo/video shooters may be happier around 256GB–512GB , while serious video shooters can very quickly find themselves looking at 1TB or more . Court's 10-Point Memory Card Checklist Buy the right card for the camera. Compatibility comes first. Prioritize write speed for shooting and read speed for transferring files. Pay attention to sustained write speed for video. Look at ratings such as V30, V60, and V90 and check what the camera requires. Don't bargain-hunt too aggressively. Buy good cards from reputable brands and trustworthy retailers. Use a real memory-card case. Loose cards rattling around in the bottom of a camera bag are asking for trouble. Have a system for full vs. empty cards. Face-up/face-down, separate cases, labels—whatever works. Just make it obvious. Format cards in the camera only after the photos are safely backed up. Import → Backup → Verify → Format Don't remove cards while they're being accessed. Give the camera or computer a few seconds to finish its work. Retire suspicious cards. Court's philosophy is simple: if a card starts giving errors, transfer problems, or anything else that makes him nervous, it doesn't come on an important trip. Remember that a memory card is temporary storage—not an archive. Build a proper backup workflow for both the trip and when you get home.
