Buying Guide

Speed Class and Video Performance

When choosing a 64GB SD card, the speed class determines what kind of video you can record reliably. For Full HD (1080p), a Class 10 rating is sufficient, as seen on the SanDisk Ultra 64GB Class 10 SDXC UHS-I Memory Card. However, if you plan to shoot 4K UHD video, you need a card with UHS Speed Class 3 (U3) and Video Speed Class 30 (V30). Both the SANDISK 64GB Extreme SD Memory Card and the SANDISK 64GB Extreme PRO SDXC UHS-I Memory Card meet those requirements, making them ideal for modern action cameras and mirrorless systems.

For those who need the fastest possible transfer speeds, the Extreme PRO offers read speeds up to 200MB/s and write speeds up to 90MB/s. That is a significant improvement over the Ultra models, which top out at 100MB/s read. If you frequently move large files, consider the Extreme range.

Capacity and Storage Needs

64GB is a sweet spot for many users. It holds roughly 7000 photos from a 20MP camera or about 90 minutes of 4K video. All four cards we reviewed offer 64GB, but their performance differs. The SanDisk 64GB Ultra SDXC UHS-I Memory Card is great for everyday snapshots and casual video. If you need more space, you might consider stepping up to 128GB or 256GB. Our Best 256GB SD Cards article can help you decide.

Remember that actual usable storage is slightly less due to formatting and system files. But 64GB still gives you plenty of room for a day of shooting without worrying about running out of space.

Durability and Reliability

SanDisk SD cards are known for their ruggedness. The Ultra models are waterproof, temperature proof, X-ray proof, magnet proof, and shockproof. The Extreme and Extreme PRO cards go even further, engineered to perform in extreme conditions despite rough handling. Whether you are hiking in the rain or shooting in freezing temperatures, these cards keep your data safe. For outdoor adventures, you might also like our Outdoor-Ready Essentials guide.

Compatibility with Devices

All four cards are SDXC UHS-I, which means they work with most modern cameras, camcorders, and laptops that have an SD card slot. Older devices that only support SDHC may not recognize them. The Ultra models are best for point-and-shoot cameras and camcorders, while the Extreme series is optimized for DSLRs, mirrorless cameras, and 4K drones.

Final Thoughts

After evaluating all four SanDisk 64GB SD cards, we recommend the SANDISK 64GB Extreme PRO SDXC UHS-I Memory Card for professionals and serious enthusiasts who demand the fastest read and write speeds for 4K video and burst photography. For everyday users who need a reliable, affordable card for Full HD video and casual shooting, the SanDisk 64GB Ultra SDXC UHS-I Memory Card is an excellent choice. Both offer proven SanDisk quality and come with the peace of mind of built-in durability.
