USB 3.0 SD and MicroSD reader

The IOGEAR GFR304SD is an external USB 3.0 card reader that handles SD, SDHC, SDXC, MicroSD and MMC media. It connects through a standard USB 3.0 port and draws power from the bus, so no separate adapter is needed. Its compact 2.5" x .8" x .4" black housing makes it easy to carry in a laptop bag or pocket.

Upgrading from USB 2.0 readers

Swapping an older USB 2.0 reader for this model raises the peak transfer rate to 5 Gbps, which shortens offload times for high-capacity SDXC and MicroSDXC cards. The jump is worth it when you regularly move multi-gigabyte photo or video batches and want the bus speed to keep pace with the card's own rating. It does not support CompactFlash or Memory Stick formats.

Check your ports and media

Verify that your computer has a free USB Type-A port for the 3.0 connection; the reader will fall back to USB 2.0 speeds on older ports. Confirm your cards are SD, SDHC, SDXC, MicroSD or MMC types, as other formats are not accepted. No driver installation is required on modern Windows or macOS systems.

Perguntas sobre este artigo

How much desk space does the 2.5 by 0.8 by 0.4 inch GFR304SD reader occupy?

The reader measures 2.5 inches long, 0.8 inches wide and 0.4 inches thick, so it fits beside a laptop or behind a monitor without crowding other ports.

What is the common mistake when plugging the GFR304SD into a USB 3.0 port for the first time?

Users often insert the cable upside down or into a USB 2.0 port; align the blue-tabbed USB 3.0 plug with the matching blue port and push straight in until it clicks.

Which card-slot springs or contacts on the GFR304SD tend to wear out first and need replacement?

The SD and microSD slots share the same spring-loaded eject mechanism; if a card sticks, the whole reader is replaced because the mechanism is not user-serviceable.
