SanDisk Ultra 64GB SDXC Twin Pack

This twin pack supplies two 64GB SDXC cards rated Class 10 and UHS-I. Each card delivers up to 48MB/s read speed and 15MB/s write speed. They suit compact and mid-range point-and-shoot cameras that record Full HD video. The cards operate between 2.7V and 3.3V.

Upgrade from slower or smaller cards

Replacing a Class 4 or Class 6 card removes the bottleneck that causes dropped frames during Full HD recording. The jump is worth it when your camera writes continuously at 15MB/s or higher. Older cards below 32GB also limit session length before you must offload files.

64GB capacity with Class 10 headroom

Each card holds roughly 64GB of photos and Full HD footage before filling. Sustained write performance stays at 15MB/s, so long clips record without interruption. The limit appears when you need 4K bit-rates or burst speeds above 48MB/s, which exceed the UHS-I Class 10 rating.

Questions about this item

What are the exact dimensions of the 64GB card so I can check it fits my camera slot?

Each card measures 24mm by 32mm by 2.1mm, matching the standard full-size SD form factor used in most cameras.

Is there anything special about inserting these UHS-I cards compared to older SD cards?

Insert the card label-side up until it clicks; the 9-pin interface aligns automatically and the only common mistake is not pushing it fully home.

How long before the Class 10 rating might drop and the card need replacing?

The Class 10 and UHS-I ratings are permanent specifications; replacement is only needed if the 64GB capacity fills or the card suffers physical damage.
