SanDisk Extreme 64GB SDHC UHS-I U3 90MB/s 600X 10-pack

Ten-card kit for continuous shooting

This pack supplies ten SanDisk Extreme SDHC cards, each rated at 64 GB, giving 640 GB total capacity. The UHS-I U3 specification supports sustained write speeds up to 40 MB/s, making the set suitable for photographers and videographers who need multiple cards for extended sessions. Cards are rated Class 10 for Full HD and 3D video capture. Built-in ECC helps maintain data integrity across every card.

Sustained write performance under load

The 40 MB/s write rating is maintained across the UHS-I bus rather than only in short bursts, so continuous RAW bursts or long video clips stay smooth. Advanced ECC operates during every read and write cycle, reducing errors when cards run warm during prolonged use. Temperature, water, shock and X-ray proofing protects the media when shooting in harsh environments. Reliability is verified through SanDisk professional testing standards.

Upgrade from slower or smaller cards

This kit replaces lower-speed Class 10 or U1 cards that bottleneck burst rates or 4K workflows. The 600X read rating accelerates offload times when ingesting large batches. Photographers carrying multiple smaller cards can consolidate to fewer, larger cards without sacrificing speed. The jump is worthwhile when current media limits shot-to-shot pace or requires frequent swaps during events.
