480 megabits/s
the answer is USB 2.0 High Speed
The theoretical maximum data rate in USB 2.0 is 480 Mbit/s (60 MB/s) per controller and is shared amongst all attached devices. Some chipset manufacturers overcome this bottleneck by providing multiple USB 2.0 controllers within the Southbridge. It should be noted that USB 3.0 has now been released and operates at a theoretical top speed of 5Gbit/s.
USB Transfers data at a maximum rate of 480 megabits per second.
USB 1.0 has the maximum speed of 1.5Mbps. USB 1.1 is a bit faster at 12Mbps. USB 2.0 is the fastest currently at 480Mbps. USB 3.0 will be released in 2010 and that will have a maximum speed of 4.8Gbit/s.
High Speed usb is 2.0 now some comptuer have a 2.0 speed usb port some are slower. So if it says "You have plugged in a highspeed usb to a slower port" Or w/e then that means it will just be slower. Newer / Old but expensive comptuers have high speed USB ports. Hope this helped
Around 35MB/s 35 Mega Bytes per second
The original USB 1 system had a speed of 12 megabits per second
USB 1.0 and 1.1 had a specified maximum data transfer rate of 12 Mbits/s. USB 2.0 has a theoretical maximum data transfer rate of 480 Mbits/s USB 3.0 will have a theoretical maximum of 4.8 Gbits/s.
USB 1.0 has a specified data rate of 1.5 Mbit/s for "low speed" and 12 Mbit/s for "full speed" USB 2.0 has a maximum speed of 480 Mbit/s which has been being called "high speed" however, USB 3 is on the way, (to be called "super speed") and will be capable of transfer speeds up to 5.0Gbps in full duplex. FYI: 8 bits = 1 byte (roughly) 1,024 bytes = 1 Kb (kilobyte) 122Kb = 1 Mbit
12 Mbps for original and 480 Mbps for high speed.Darryl Erickson
It doesn't matter what is the speed is on the USB it depends on the computer's speed on its hardrive, internet, or both the speed is not based on the 2.0 USB, is the computer either its old or new or in between.
It is USB 2.0, the standard external data and power connection.
