What is USB 3.0?

Tuesday, January 12th, 2010 by | Filed Under: Hardware & Peripherals

Chuck from CA asks:

What is USB 3.0, exactly? Should I care? 

Heck of a question, Chuck!

With new devices coming out every day, there is a need for a faster technology to transfer data to (and from) your computer. Some devices, such as Blu-ray players and very large external hard drives, simply need to transfer data faster than what USB 2.0 is currently capable of.

3.0 cable

So, How Fast is USB 3.0?
USB 3.0 is up to 10 times faster than USB 2.0. For example, if you have a 1GB flash drive full of music, it would take 33 seconds to transfer the contents to your computer using USB 2.0. Using USB 3.0, it will only take just over 3 seconds!! Another example is if you have an HD movie that is 25GB, it would take 13 minutes on usb 2.0. It will only take 70 seconds with USB 3.0. That’s pretty fast, wouldn’t you say?

Okay – Then What happens to my USB 2.0 stuff?
No need to worry here. The makers of USB 3.0 made sure that all of the USB 2.0 devices will work on USB 3.0 ports.So if you get a new computer that has USB 3.0, you will still be able to plug in your 2.0 equipment. Remember that you will only get 2.0 speeds from the 2.0 devices, but at least they will work without costly upgrades.

Here’s to our high-speed future!
