USB 3.0 is advertised as being 10 times faster than USB 2.0. Lets find out how fast is USB 3.0 in typical everyday use.
Data transfer comparison
Let’s see how other data connections compare to USB 3.0:
As you can see compared to USB 2.0, FireWire, Sata/eSata, USB 3.0 really is superspeed!
A newly fitted USB 3.0 pci card will provide speeds of up to 4800 Mb per second compared to USB 2.0’s speed of 480 Mb per second. That’s 10 times faster.
USB is a standard connection on computers and so will be around for quite some time in the future. USB 3.0 is even faster than gigabit networks!
This is obviously impressive but there’s another reason why USB 3.0 is faster – it’s bidirectional. This means it’s able to send and transmit data at the same rate. This full duplex speed is achieved by adding four new data wires to the USB 3.0 interface.
Two are used to transmit and two are used to receive data. That means that the data transfer lanes have been doubled compared to USB 2.0 .
The new wires make the actual USB 3.0 cable slightly thicker than USB 2.0 cables but this is barely noticeable for everyday usage.
Imagine transferring 25GB’s worth of data in about a minute! That could be a movie, your music library or some data backups.
