Three-Pack USB 3.0 Card Reader

This three-pack supplies three identical USB 3.0 card readers, each with a full-size SD slot and a microSD slot. The readers connect through a standard USB Type A plug and require no driver installation on Windows, macOS, Linux or Android. They are intended for photographers, studios and anyone who needs to offload images or video from multiple cards quickly.

Sustained Transfer at 5 Gbps

The USB 3.0 interface is rated at 5 Gbps, so large batches of RAW files or high-bitrate video move at the bus limit rather than throttling after a short burst. Both slots share the same controller, allowing sequential offloads from two cards without a noticeable drop in throughput during extended sessions.

USB 3.0 Bus Limits

Actual throughput cannot exceed the 5 Gbps signalling rate of the USB 3.0 connection, and real-world speeds depend on the host controller and the card's own read ceiling. The reader adds no encryption, RAID or proprietary protocol; it simply passes the native SD or microSD signal to the host over the standard bulk endpoint.

Questions about this item

Does the USB 3.0 5Gbps reader get hot or draw much power during all-day transfers?

The compact body weighs only .018 kilograms and is described as having strong heat dissipation, so it stays cool during extended use.

What must I already own — specific cards or ports — for the dual-slot reader to work?

You need a free USB Type A port and any supported SD, SDHC, SDXC, Micro SD, Micro SDHC or Micro SDXC card including UHS-I.

Will the 3.0 adapter slow down if I plug it into an older USB 2.0 port on my current laptop?

It will fall back to 480 Mbps on a USB 2.0 port, but still reads every supported card format without extra drivers.
