Match your camera's needs with the right SD card. Learn about speed classes, UHS-I vs UHS-II, and pick the best SanDisk card for 4K video or burst shooting.
Quick answer
Choose an SD card that matches your camera's speed class and your shooting style. For 4K video or burst shooting, look for V30 or higher; for casual photos, V10 is enough.
Understand speed classes
Speed classes indicate the minimum sustained write speed. V10 guarantees 10 MB/s, V30 guarantees 30 MB/s. For 4K video, V30 is recommended to avoid dropped frames; V10 works for 1080p or casual shooting.
UHS-I and UHS-II refer to the bus interface. UHS-II cards are faster but require a compatible camera and card reader. Most cameras support UHS-I; check your camera's manual before buying UHS-II.
Capacity vs. price trade-off
Higher capacity cards hold more photos and video, but cost more per GB. A 64GB card is a sweet spot for most photographers, offering enough space for a day of shooting without overspending. 256GB suits heavy shooters who don't want to swap cards often.
Consider your workflow: if you offload files daily, a 64GB card is practical; if you travel long without a computer, 256GB saves hassle.
Decision rules for choosing your SD card
- Check your camera's manual: Identify the supported card type (SDHC vs SDXC) and bus interface (UHS-I vs UHS-II). Most cameras accept SDXC UHS-I, but verify before buying. If your camera only supports SDHC, avoid SDXC cards.
- Match speed to your shooting: For 4K video or high-speed burst shooting, choose a V30 card (or faster). For 1080p video or stills, V10 is sufficient. Borrow a friend's V30 card to test your camera's performance before upgrading.
- Decide capacity based on usage: Choose 64GB for casual shooting or daily offloading; choose 256GB for travel or extended sessions without access to a computer. If you shoot RAW, estimate file sizes to ensure capacity is enough.
