USB3.0 Card USB Flash Drive
What is the USB3.0 card usb flash drive?
The USB 3.0 card flash drive improves upon the standard USB 2.0 interface by adopting a USB 3.0 port. Its core advantage lies in maintaining the card flash drive’s portable convenience while achieving USB 3.0’s high-speed transfer rates, addressing the pain point of slow large-file transfers common in traditional USB 2.0 card flash drives.
The most noticeable feature of USB 3.0 flash drives is their appearance: the 3.0 port is blue, and while the thickness remains the same as 2.0 models, transfer speeds are significantly faster. USB 3.0 card flash drives are backward compatible with USB 2.0/USB 1.1 devices (such as older computers or in-car USB ports).
