8x usb 2.0意思

"8x USB 2.0" is not a standard term used to describe USB ports or devices. The "x" in "8x" is typically used in the context of CD or DVD drives to indicate the drive's read or write speed, where "x" is a multiplier for the standard CD read speed of 1x, which is approximately 1.48 Mbit/s.

However, if you're referring to "8 USB 2.0 ports," that would mean there are eight individual USB 2.0 connectors or ports. USB 2.0 is a specification for Universal Serial Bus (USB) technology that was introduced in April 2000 and has a maximum data transfer rate of 480 Mbit/s.

If you're seeing "8x USB 2.0" in a product description or technical documentation, it might be a typo or a miscommunication. It's more likely to be referring to eight USB 2.0 ports or connectors. If you're unsure, it's best to consult the manufacturer or the product's documentation for clarification.
