TOPRAM CR03 USB 2.0 Card Reader

The TOPRAM CR03 is a single-slot external card reader that connects through a USB 2.0 port. It accepts SD, SDHC and SDXC memory cards up to 64 GB capacity. The device is aimed at photographers and mobile users who need a simple way to move images or files from a card to a computer. No drivers are required on supported operating systems.

Check host port and card capacity

Verify that the host computer provides a standard USB Type-A socket for the reader's plug. The reader supports cards up to 64 GB; larger cards will not be recognised. Confirm the memory card format is SD, SDHC or SDXC before inserting it. Compatibility is listed for Windows and Mac OS 9.2 or later.

Sustained transfer at USB 2.0 speeds

Under continuous use the reader operates at USB 2.0 bulk-endpoint rates, so long sequential reads or writes settle at the bus limit rather than the card's peak speed. The single-slot design means only one card is active at a time, avoiding bandwidth sharing. No active cooling is present, so the enclosure may become warm during extended transfers.

Questions about this item

Does the TOPRAM CR03 include a memory card or must I buy one separately?

The package contains the single-slot USB 2.0 reader only; a compatible SD, SDHC or SDXC card up to 64 GB must be purchased separately.

Which capacity card should I choose for the CR03 reader?

Any SD, SDHC or SDXC card up to 64 GB is supported; pick 4 GB, 8 GB, 16 GB, 32 GB or 64 GB according to your storage needs.

What transfer speed will I see when the CR03 is connected to a PC?

The USB 2.0 interface limits real-world throughput to the standard 2.0 rate, so large file copies will run at USB 2.0 speeds regardless of the card used.
