Buying Guide
Capacity needs
Camera storage requirements vary by shooting style. Day trips with 128GB cards can hold thousands of RAW files or several hours of 4K video, but extended shoots or high-frame-rate video may demand 256GB or larger. If you work with RAW photos, consider larger capacities to reduce offload frequency. For casual shooting or travel, 64GB to 128GB may be sufficient, with the option to swap cards as needed.
Speed and performance
Speed class matters for video and continuous shooting. Look for C10, U1, or U3 ratings and V30 for reliable 4K capture. Read speeds impact how quickly you offload files to your computer, while write speeds affect real-time recording. The SanDisk Extreme PRO cards offer very high read speeds and strong write speeds for demanding workflows, while Ultra cards provide solid everyday performance at a lower price point.
Camera compatibility
Ensure your camera supports the card format (SDXC vs SDHC) and capacity. Most modern cameras handle SDXC cards up to 128GB or 256GB, but older cameras may have limits. If your camera supports UHS-I and 4K recording, choose a card with U3/V30 ratings to ensure stable performance during video capture.
Reliability and data protection
Durability is important for field work. Many popular brands offer durable construction and reliable error correction, along with warranties. Some manufacturers also provide data recovery services or extended coverage, which can be valuable if a card becomes corrupted. When shooting events or weddings, consider a backup strategy that includes a second card and routine offloads to a computer or external drive.
Value and overall fit
Balance capacity, speed, and price. For 4K video, prioritize speeds that meet or exceed the camera’s requirements (V30 or higher). For still photography and burst shooting, faster write speeds reduce lag between frames. If you frequently swap between different camera bodies, a dependable, branded card with solid warranty is worth the premium for peace of mind.
Practical recommendations
Based on typical needs, the following guidance applies: use 128GB cards for mid-range cameras and everyday 4K shooting; choose 256GB cards for long sessions or high-volume RAW workflows; favor cards with V30 or higher for 4K; have a spare card or two on hand for critical shoots. Always format in-camera after confirming compatibility to ensure optimal performance.
