My laptop is Lenovo T400. I wonder what kind of portable external HDD you would recommend me to buy, in terms of protocols?

For example, if I am correct, my Lenovo T400 doesn't have USB 3.0 port. I am interested in buying Western Digital® My Passport® Essential™ 1TB Portable Hard Drive-USB 3.0. I wonder if my T400 cannot use that portable HDD with USB 3.0? Is it possible to install something like USB 3.0 driver on my Ubuntu 12.04 on my T400 in order to use that portable HDD with USB 3.0?

Thanks!

As it is, this question is a shopping recommendation and, therefore, off topic. –  Dennis Aug 11 '12 at 14:16

@Dennis: I think I asked more about matching problem than shopping recommendation. –  Tim Aug 11 '12 at 14:18

I wonder what kind of portable external HDD you would recommend me to buy, in terms of protocols? is clearly a shopping recommendation. The rest of the question is on topic, of course. –  Dennis Aug 11 '12 at 14:21

A USB 3.0 Portable hard drive will work in a USB 2.0 (or even 1.1) port. However, you will not get the extra speed provided by USB 3.0.

USB3 and USB2 are physically different. This isn't a driver issue. –  Dennis Aug 11 '12 at 14:17
    
Just to add to Dennis's comment. USB 3.0 has two extra wires that when plugged into a USB 2.0 socket don't connect to anything. It is these two extra wire that help it to achieve the greater speeds. –  user1291332 Aug 11 '12 at 14:28
