Choosing an SD card means balancing speed, capacity, and durability. This guide explains what to look for and which cards suit different shooting needs.
Quick answer
For most camera users, a UHS-I SD card with V30 speed class offers the best balance of performance and value. The SanDisk 32GB Extreme Pro SDHC is a reliable choice for high-quality stills and 4K video.
Speed isn't just about burst shooting
A card's speed rating affects how quickly your camera clears its buffer after a burst of shots and how smoothly it records video. The Video Speed Class (V30) ensures minimum write speeds of 30MB/s, which is enough for 4K video at common frame rates. If you shoot raw bursts or high-bitrate 4K, look for V30 or higher.
One trade-off: faster cards (V60, V90) cost significantly more and may not improve performance in cameras that can't fully use that speed. Check your camera's manual for its maximum supported write speed before spending extra.
Capacity: more isn't always better
Larger cards hold more photos and video, but they also concentrate your risk. If a card fails, you lose everything on it. Many photographers prefer using multiple smaller cards (e.g., 32GB or 64GB) to spread that risk across shoots. Also, some older cameras may not support SDXC cards (64GB and above) or exFAT formatting. The SanDisk 32GB Extreme Pro is SDHC, so it's compatible with a wider range of devices.
The 1TB SanDisk Extreme Portable SSD is a great companion for offloading cards in the field, but it's not a replacement for an in-camera memory card.
Durability and reliability matter on location
Memory cards live in your camera bag, pocket, or backpack. Cards like the SanDisk Extreme Pro are shockproof, waterproof, and x-ray proof, which adds peace of mind when shooting outdoors or traveling. A card that can survive a drop or a splash is worth the small premium over basic models.
For simple file transfers or emergency backups, a budget USB flash drive like the Hama 64GB USB Rotate Flashpen can be handy, but don't rely on it as your primary camera storage.
How to choose your SD card
- Check your camera's speed limit: Look up the maximum write speed your camera supports. Buying a card faster than that wastes money.
- Match speed class to your use: For 4K video or raw bursts, choose at least V30. For casual JPEG shooting, a Class 10 card is sufficient. If you shoot mostly stills, V30 is a safe baseline.
- Pick capacity by workflow: Use 32GB or 64GB cards for daily shooting to limit loss if a card fails. Reserve larger cards (128GB+) for long events or extended trips. Always format the card in your camera before first use.
- Consider durability features: If you shoot outdoors or travel, choose cards that are water, shock, and x-ray proof. For studio use, basic cards may be fine.
