64GB SDXC Card with R1 Reader

The TOPRAM SDXC card provides 64GB of storage for cameras, camcorders, phones and other portable devices. It carries a Class 10 speed rating with UHS-1 support for reliable capture of photos and video. The bundled R1 reader lets you transfer files to a computer without a built-in card slot.

R1 Reader adds direct USB access

The included R1 reader connects the card to a USB port so you can offload images and video on any compatible Windows system. It removes the need for a dedicated card slot or separate adapter. The reader works with the supplied card and other SDHC or SDXC media you may already own.

UHS-1 bus limits peak throughput

The UHS-1 interface caps maximum read performance at roughly 20MB/s and write speeds between 10MB/s and 15MB/s. Sustained rates will vary with the host device and file sizes. The card meets the minimum 10MB/s sequential write requirement for Class 10 but is not suited for high-bitrate 4K or rapid burst workflows.

Questions about this item

How often will the TOPRAM 64GB SDXC card need replacement under normal camera use?

The card uses standard NAND flash with no moving parts; replacement is only needed if the card is physically damaged or reaches its write-cycle limit after very heavy long-term use.

What speed limit appears first during continuous video recording on this card?

Sustained write speed settles between 10 MB/s and 15 MB/s, so the write throughput ceiling is reached before the 20 MB/s read ceiling during long recordings.

Does the TOPRAM 64GB SDXC card generate noticeable heat or draw extra power during all-day shooting?

The card draws minimal power from the host device and stays cool to the touch even during extended read or write sessions.
