Compact USB 3.0 Card Reader

The uni USUNIASD01 is a USB 3.0 card reader that accepts full-size SD and microSD cards simultaneously. It supports UHS-I cards up to 2TB capacity and works with Windows, macOS, Linux and Chrome OS devices that have a USB-A port. Photographers and laptop users can transfer files from two cards without swapping adapters.

Check Your Ports And File Systems

Verify your computer has an available USB-A port because the reader uses that connector. Note that transfer speed may decrease when both slots are active at the same time. On macOS or Linux, NTFS-formatted cards are read-only; format cards as exFAT if you move files between different operating systems.

Suits Dual-Slot Workflows Not Single-Card

This reader suits users who need concurrent access to SD and microSD media on USB-A laptops, desktops or compatible smart TVs. Buyers who only ever use one card type or who require a USB-C connection without an adapter should consider a different form factor. The aluminium casing runs warm during sustained transfers, which is normal for this design.
