USB 3.0 is expected to be 10 times faster than USB 2.0, up to 4.8 gigabits per minute.
The principal advantages of USB up to this point has been ease of use and relative low price.

Conversely, Firewire is similar to a direct connection to the external disk drive, and will copy files much quicker than USB. It’s favored over the more common USB for its greater effective rate and power distribution capabilities, and because it does not require a computer host.
This is a relatively new option for external drives because USB 2.0 and Firewire connected drives have been around for quite a while now. The main benefit of this eSATA technology is rate, some 4-6 times quicker than present USB 2.0 and Firewire transport speeds. You will soon be seeing an increasing number of products that provide eSATA as an alternative. Most external hard drives will soon be capable of three ports – but a few are only capable of either USB or Firewire. One thing to keep in mind when you are picking the best external hard drive.
So how do I pick?
All three technologies will find the task done. Your choice will come down to price and simplicity of use. If you’re on a limited budget, then USB will probably be the ideal alternative, whereas if speed is what’s valuable to you, and you’re willing to pay for it, Firewire or eSATA will do the job best.
Whatever you opt for, backing up your computer files is now simpler than ever. There is actually no justification today, so do it!
An external hard drive is a piece of hardware that is nearly essential for every individual who owns a computer. While many men and women go with no external drive, having a mobile hard disk can be helpful in more ways than one. For people who have significant data that they cannot afford to lose, a mobile hard disk lets them keep a safe copy of the data files.
