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?
