TOPRAM OEM64GSD-Blank 64GB SDXC Card

This TOPRAM OEM64GSD-Blank card provides 64GB of Secure Digital Extended Capacity storage. It operates with a UHS-1/Class 507 speed rating. The card delivers read speeds up to 20MB/s and write speeds up to 15MB/s. It is supplied in OEM bulk packaging without a retail box or sticker.

Suits cameras and devices needing basic Class 10

This card suits photographers and videographers using SDHC or SDXC compatible cameras, camcorders, phones or GPS units that require Class 10 speeds. It supports Windows 7, Vista and XP for file transfers. Users needing sustained write speeds above 15MB/s for high-bitrate 4K video or rapid burst shooting should look at higher-specification cards.

Fits SDXC slots and frees internal device storage

The card fits any host device with an SDXC or SDHC slot for immediate capacity expansion. It frees up internal memory on phones, tablets or cameras by offloading photos, videos and music files. No additional drivers are required for the listed operating systems. The OEM packaging means no retail accessories or software bundles are included.

Questions about this item

Which devices accept a 64GB SDXC card for storage expansion?

Cameras, camcorders, phones, PDAs, MP3 players, GPS units and other portable electronics with an SDXC slot will recognise the 64GB capacity.

Will a reader that only supports SDHC work with this UHS-1/Class 507 card?

No, the card follows the SDXC specification so it requires an SDXC-compatible host; an SDHC-only reader cannot address the 64GB volume.

How can I confirm the card delivers its rated Class 10 performance after formatting?

Run a sequential read/write test — sustained reads near 20MB/s and writes near 15MB/s indicate the UHS-1/Class 507 rating is being met.
