Buying Guide: What to Look for in an SD Memory Card

Speed Class and Data Transfer Rates

The speed of an SD card determines how quickly you can write photos or videos and read them back. For 4K video recording or burst shooting, look for UHS Speed Class 3 (U3) or Video Speed Class V30. The SanDisk 32GB Ultra offers up to 100 MB/s read speed, which is plenty for Full HD video and everyday photography. If you are building a gaming PC, you might also benefit from fast storage—see our best gaming graphics cards for budget builds for compatible components.

Capacity: How Much Do You Need?

SD cards range from 32GB to 1TB. The 32GB capacity is ideal for casual shooters who don’t need to store thousands of raw files. It holds about 1,000 high-resolution JPEGs or 30 minutes of 4K video. For larger projects, consider 64GB or 128GB. Our pick, the SanDisk 32GB Ultra, balances affordability and storage for everyday use.

Compatibility with Your Devices

Not all SD cards work with every device. Check if your camera, drone, or laptop supports SDHC (up to 32GB) or SDXC (64GB and above). The SanDisk 32GB Ultra is an SDHC card, compatible with most modern cameras and laptops. For audio enthusiasts, pairing a reliable card with a high-quality sound card can improve workflow—read our top creative sound cards for gaming for recommendations.

Durability and Reliability

Memory cards face extreme conditions: temperature swings, moisture, and accidental drops. SanDisk cards are known for being shockproof, temperature-proof, and waterproof. The Ultra series includes built-in error correction to prevent data corruption. For long-term storage, always format the card in your device before first use.
