The top speed of USB 3.0 is 5 Gbps (gigabits per second). This standard, also known as SuperSpeed USB, allows for significantly faster data transfer rates compared to its predecessor, USB 2.0, which has a maximum speed of 480 Mbps. USB 3.0 achieves this increased speed through improved data encoding and more efficient use of bandwidth.
The speed of a USB 2.0 port varies, depending on the hardware being used. However, the top speed the 2.0 port can reach is 480 Mbit/s.
All of the USB devices themselves as Hi-speed. USB 3.0, is the recent hi-speed USB.
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 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.
The Generic USB Hub is a HI-SPEED USB device and will function at reduced speed when plugged into a non-HI-SPEED port
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.
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.
Super Speed USB is faster and is usually identified by a blue port or wire. Basically USB 2.0 is High Speed (480Mbps) and USB 3.0 Super Speed (5Gbps).
The top speed of Apollo 11 during its journey to the Moon was approximately 24,790 miles per hour (39,897 km/h).
USB 2.0
Perhaps a computer processing unit from about 2010.
