High-Speed Data Transfer
For computer connections, the two slots for SD and microSD cards support UHS-I (up to 104MB/s), while the CompactFlash slot supports Type I (up to 167MB/s). This enables high-speed data transfer for high-resolution photos and large video files, when combined with a compatible computer. The device connects to the computer via a USB-A connector that supports USB 5Gbps.
This reader supports reading and writing for UHS-II and SD Express compatible cards, though data transfer speeds for reading and writing will be at UHS-I speeds. The design aims to minimize compatibility issues between connected devices, ensuring stable data quality between the computer and the memory card reader, based on signal authentication tests.
Driver-Free, Compact, and Cable-Integrated Design
No dedicated drivers or installation are required; simply connect the device to a computer’s USB port for immediate use. Its slim and compact body, approximately 1.5 cm thick, allows it to be easily stored in a bag or gadget pouch for portability. The integrated cable is approximately 50 cm long, providing ample length for convenient use without the worry of forgetting or losing it.
