Two-card kit for high-speed capture

This pack contains two SanDisk Extreme SDHC UHS-I cards, each with 64 GB capacity for a combined 128 GB. They are built for photographers and videographers who need reliable storage for continuous shooting and Full HD video recording. The U3 speed class and 600X rating support sustained write performance during demanding capture sessions.

Step up from standard Class 10 cards

Standard Class 10 cards often lack the sustained write speed needed for uninterrupted Full HD or 3D video. These cards deliver up to 40 MB/s write speed and U3 performance, making the upgrade worthwhile when shot-to-shot latency or dropped frames become an issue. The 90 MB/s read speed also accelerates file offload to a computer.

Fits any SDHC or SDXC slot with UHS-I support

Each card works in cameras, camcorders, or card readers that accept SDHC media and the UHS-I bus. The error correction engine helps maintain data integrity during heavy read and write cycles. Temperature, water, shock, and X-ray resistance protect the media in harsh environments, freeing you to focus on the shoot rather than card handling.

Questions about this item

Will the two 64GB cards fit a standard SDHC slot?

Yes, each card follows the SDHC form factor so it slides into any standard SDHC or SDXC slot without an adapter.

What is the most common mistake when installing these cards in a camera?

Inserting the card upside-down or not pushing it until it clicks; the label should face the same way as the battery door and you must feel the latch engage.

How often should I replace the cards if I record Full HD video at the rated write speed?

The built-in ECC engine and temperature, water, shock and X-ray proofing mean the cards last for years; replace only if a device reports write errors or the lifetime limited warranty is invoked.
