"External hard drives are becoming almost as popular as flash drives and it isn't hard to see why. They are extremely easy to install and offer the portability that internal drives simply don't offer out of the box. This makes them great for users on the go needing to store large amounts of data or need an easy to use yet still cheap backup system. Bus powered external drives are even more portable than their non-bus powered brethren, however their size usually requires them to sacrifice some speed as they usually offer only USB support. Buffalo thinks that this shouldn't be the case which is why we are taking a look at the Buffalo 320GB MiniStation Turbo USB portable hard drive, a drive they claim to be up to 64% faster than the competition."
