Learn how to pick the right memory card for your camera by matching capacity, speed, and type to your shooting style and gear.
Quick answer
Choose a memory card based on your camera's format support, the speed you need for your shooting style, and the capacity that matches how you store and transfer files. For most photographers, a 128GB Class-10 SDXC UHS-I card offers the best balance of speed, capacity, and price.
Match the card format to your camera
The first decision is physical size. Most consumer and enthusiast cameras accept SD cards, while professional models often use CFexpress or XQD. Your camera's card slot dictates the format, so check the manual before buying. If you have a newer mirrorless camera, it may support UHS-II cards for faster transfer speeds, but a UHS-I card still works if the camera accepts it.
Memory cards are not one-size-fits-all. A card that works in one camera may not fit another, and using the wrong speed class can slow down burst shooting or video recording.
Decision rules for picking a memory card
- Match the card type to your camera slot: Check your camera manual for the supported card format: SD, microSD, or CFexpress. Using the wrong physical format means the card will not fit the slot. Confirm the slot type before buying.
- Pick speed class by shooting style: For 4K video or burst shooting, choose a UHS-I Class 10 card or faster. For casual photos, a Class 10 card is enough. If you shoot RAW bursts, go for UHS-II or V60/V90-rated cards. Match the speed class to your camera's continuous shooting and video bitrate.
- Match capacity to your workflow: Choose 64GB for everyday photos, 128GB for mixed photo and 4K video, and 256GB or more for long shoots or 8K footage. Remember to account for backup needs. Buy two smaller cards instead of one giant card so a failure doesn't wipe your whole shoot.
