Ready for 4K capture

The Transcend 300S 64GB SDXC card targets photographers and videographers who need reliable storage for advanced DSLR cameras and HD camcorders. It uses 3D NAND flash and meets UHS-I U3 and V30 specifications for sustained 4K recording.

UHS-I bus ceiling

The UHS-I interface caps sequential reads at 95MB/s and writes at 45MB/s, so sustained throughput cannot exceed those figures. Devices limited to the UHS-I bus will not benefit from faster card ratings.

64GB practical headroom

At 64GB the card holds thousands of photos and hours of Full HD footage, but 4K video consumes space quickly and may fill it during long sessions. Users needing more room must choose a higher-capacity model.

Questions about this item

Is the 64GB capacity enough for 4K video or should I choose a larger 300S card?

The 64GB 300S card supports V30 for 4K recording; larger 300S cards up to 512GB simply give more space for the same sustained write performance.

Will I actually see the 95MB/s read speed when copying files to my PC?

The 95MB/s figure is the maximum sequential read; real-world transfer depends on your card reader and USB port, but the card itself is rated for that peak.

Does the UHS-I interface limit the 45MB/s write speed needed for V30 4K capture?

The card meets U3 and V30 with a 45MB/s sustained write rating, which the UHS-I bus supports for 4K video recording.
