Twin 64GB cards for cameras

This pack supplies two SanDisk Ultra SDHC cards, each 64GB, giving a combined 128GB of storage. They are rated Class 10 with maximum read speeds of 80MB/s. The cards suit compact and mid-range point-and-shoot cameras that record Full HD video and high-resolution photos.

Class 10 bus limits real throughput

The Class 10 rating guarantees a minimum sustained write speed of 10MB/s, while the quoted 80MB/s is a peak read figure. Actual transfer rates depend on the host device, card reader and USB connection; the slowest link in the chain determines the final speed. Capacity is labelled using decimal gigabytes, so the operating system will report roughly 7–10% less usable space.

Check your camera slot and reader

Before ordering, confirm that your camera accepts SDHC cards and supports the Class 10 speed class. Verify that your card reader or computer slot can handle SDHC capacities and UHS-I speeds to avoid bottlenecks. The cards are waterproof, temperature-proof, X-ray proof, magnet-proof and shockproof for rugged use.

Questions about this item

Should I buy the 128 GB twin pack or look for a single larger card?

The pack gives you 128 GB total as two 64 GB cards, which lets you swap cards mid-shoot and spreads risk if one card fails.

Will I actually see 80 MB/s when copying photos to my laptop?

The 80 MB/s figure is the maximum read speed; real-world transfer rates depend on your card reader and USB connection, so you may see lower speeds.

What does the Class 10 rating guarantee for video recording?

Class 10 guarantees a minimum sustained write speed of 10 MB/s, enough for Full HD video on most compact and mid-range cameras.
