You’ve just bought a new camera or tablet, and you need a reliable memory card to store your photos and videos. Class 10 SD cards offer the speed and capacity you need for Full HD recording and everyday use. In this guide, we review two top options from SanDisk and Gigastone to help you choose the best class 10 SD card for your needs. For more demanding photography work, see our list of top high performance SD cards.

Buying Guide

Speed Class and Performance

Class 10 certification guarantees a minimum sequential write speed of 10 MB/s, which is essential for recording Full HD video without dropped frames. Both the SanDisk and Gigastone cards exceed this baseline, offering up to 100 MB/s read speeds. For burst photography or 4K video, you may want to step up to a U3 or V30 card. Our high performance SD card guide covers those faster options.

Capacity and Storage Needs

Consider how much data you typically capture. The SanDisk 64GB card holds thousands of photos or hours of Full HD footage, making it ideal for a primary camera. The Gigastone 32GB 2-pack gives you two cards for separate devices or as a backup pair. If you use dash cams or security cameras, you might prefer high endurance micro SD cards designed for continuous recording.

Durability and Reliability

Memory cards face temperature extremes, moisture, and physical shocks. The Gigastone cards are waterproof, temperature-proof, x-ray-proof, shock-proof, and magnetic-proof. SanDisk cards are also built to withstand tough conditions. For outdoor adventures, check our rugged SD card picks for extra protection.

Compatibility and Device Support

Class 10 SD cards work with most cameras, camcorders, laptops, and tablets that accept SD or SDHC cards. The SanDisk is an SDXC card (64GB), while the Gigastone is SDHC (32GB). Ensure your device supports the format. For a full overview of compatible cards, visit our Cards category page.

Final Thoughts

Both the SanDisk 64GB Ultra and the Gigastone 32GB 2-Pack are excellent choices for class 10 SD cards. The SanDisk offers a larger single capacity for heavy users, while the Gigastone provides two cards for multiple devices or backup. For those who need a single, high-capacity card, the SanDisk 64GB Ultra SDXC UHS-I Memory Card is ideal. If you prefer having two cards for different cameras or as a spare, the GIGASTONE 32GB SD Card 2-Pack, Camera offers great value. Whichever you choose, you’ll get reliable class 10 performance.
