The Maxtor OneTouch 4 Mini has a lot of things that really make it an attractive buy, but most are not what you look for in a typical hard drive. Instead of blazing speed and low CPU usage, the OneTouch offers extreme portability because of its small size, a rather large storage capacity, and the ability for it to run without an external power adapter. These features are amazing, because who dosen't want to carry around 250Gb of storage in a device about the size of an iPod.
