Product identity

The Koah KO-CR1 is a USB 3.0 card reader that accepts SDXC, SDHC, SD, microSDXC, microSDHC, microSD, MMC and RS-MMC media. It serves photographers, videographers and office workers who need quick access to multiple card formats from a single desktop device.

Installation experience

The reader requires no driver installation and works immediately when plugged into a USB Type-A port on Windows or macOS systems. It supports USB 3.0, 2.0 and 1.1 hosts, so the only common issue is reduced transfer speed when connected to an older 2.0 or 1.1 port instead of a 3.0 port.

Sustained transfer behaviour

The device is rated for data transfer rates up to 5000 Mbps over the USB 3.0 interface. Actual sustained throughput depends on the inserted card’s own read and write limits, so long transfers will settle at the slower of the card speed or the host controller capability.

Questions about this item

How do I confirm the reader is transferring at the full 5000 Mbps rate after plugging it in?

Connect a UHS-I card, copy a large file, and verify the sustained throughput reaches the 5 Gbps ceiling in your OS transfer dialog.

Which cards and cables are included in the package versus what I must supply?

The box contains only the KO-CR1 reader with its fixed USB Type A connector; all SDXC, SDHC, SD, microSDXC, microSDHC, microSD, MMC and RS-MMC cards must be purchased separately.

Should I choose a different version of the KO-CR1 for faster speeds or extra ports?

The KO-CR1 is offered in a single configuration with one USB 3.0 Type A port and the stated 5000 Mbps maximum; no alternate capacity or port-count variants exist.
