Western Digital External Hard Drives

The Western Digital Passport has been the companies most successful line of portable external hard drives for several years. The sleek casing, solid build quality, reasonable speed and tons of storage space continue to keep these USB-powered 2.5" notebook hard drives popular.

The most important performance factor that comes to  mind is that you won't notice the difference between the speed of your notebook's internal hard drive and the WD Passport in "real world" use. Both drives are fast and the minor differences in transfer speeds are so insignificant that most consumers will never notice a difference.

As mentioned previously, the Passport is a completely USB-powered external hard drive, so the single 11-inch USB cable supplies both power and data connectivity. The power requirements for this drive are so minor that most laptops will have no problems supplying enough power via USB.
