Pack of five 64 GB SDHC cards

This pack contains five SanDisk Extreme SDHC UHS-I cards, each with 64 GB capacity for a combined 320 GB of storage. They are aimed at photographers and videographers who need multiple cards for extended shoots or backup workflows. The U3 speed class supports sustained write performance for Full HD and 3D video capture. Professionals who rely on consistent speed across several cards will find this bundle practical.

UHS-I bus with 90 MB/s read and 40 MB/s write

The UHS-I interface delivers up to 90 MB/s read and 40 MB/s write speeds, reducing shot-to-shot delay and speeding up file transfers. Class 10 video rating ensures steady data streams during Full HD recording. Advanced error-correction code maintains data integrity during intensive read and write cycles. The cards operate reliably across a wide temperature range without active cooling.

Replaces slower Class 10 or U1 cards

Upgrading from standard Class 10 or U1 media removes the bottleneck that causes buffer clears and dropped frames in demanding cameras. The jump is worth it when shooting bursts of high-resolution stills or recording long Full HD clips where sustained write speed matters. Users who already work with U3-rated cards at 90 MB/s read will see no practical gain. Buyers needing capacities above 64 GB per card or faster write speeds for 4K workflows should look elsewhere.

Questions about this item

How do I install the SanDisk Extreme 64GB SDHC cards in my camera, and what step do people often get wrong?

Insert each card label-side up until it clicks; the step users miss is formatting the card in the camera menu before first use so the file system matches the device.

What maintenance or replacement will the SanDisk Extreme 64GB SDHC cards need over time?

No scheduled maintenance is required; replace a card only if it shows read or write errors, physical damage, or after very heavy write cycles degrade the NAND.

What limit appears first during sustained burst shooting or video recording on the SanDisk Extreme 64GB SDHC cards?

The 40 MB/s write speed ceiling is reached before the 90 MB/s read limit, capping continuous RAW bursts or high-bitrate Full HD capture.
