64 GB SDXC card for cameras and phones

The TOPRAM TR64GSDC10 is a 64 GB Secure Digital Extended Capacity card rated UHS-1 Class 445. It targets photographers and mobile users who need reliable removable storage for everyday shooting and file transfer. A USB R3 reader is included for direct computer access.

UHS-1 bus caps real-world throughput

The UHS-1 interface limits sequential read to 15 MB/s ~ 20 MB/s and write to 10 MB/s ~ 15 MB/s. Sustained performance will not exceed these figures regardless of the host device. The Class 10 rating guarantees a minimum write of 10 MB/s for continuous recording.

Class 445 rating decides suitability

The single specification that determines fit is the UHS-1 Class 445 speed rating. It confirms the card meets the 10 MB/s minimum write required for Full HD video and burst stills. Buyers needing 4K capture or faster offload speeds should choose a higher class card.
