We recommend using a high-speed memory card in order to realize the fastest transfer rate. Currently, only high-speed memory cards, like SDXC, CF (UDMA), Micro SDXC, HX MS, etc., are able to take full advantage of the USB 3.0 card reader’s capability.

The transfer speed of the USB 3.0 card reader is limited by the specification of the memory card. The transfer speeds of the USB 3.0 and USB 2.0 card readers are almost the same. In addition, your memory card may not be able to be identified in certain older operating systems, so please make sure your system patch has been updated. Please check the lock setting on your memory card to make sure it isn’t locked. The USB 3.0 card reader supports high-speed and high-capacity memory cards. Why can’t the card reader identify my memory card? The actual transfer speed depends on the specific environment the product is used in. Taking current usage conditions into consideration, the transfer speed can achieve about 3 times that of USB 2.0. The USB 3.0 transfer rate of 5Gbps, with a theoretical transfer speed of 625MB/s, is about 10 times faster than the mainstream USB 2.0 transfer rate of 480Mb/s, which has a theoretical transfer speed of 60MB/s. Why is the transfer rate far slower than 5Gbps as promoted?
