Notebook PC users who need more storage have generally had three options: they can swap their internal hard drive with a higher capacity model, purchase a new PC with a higher capacity drive, or install external storage devices that use removable cartridges or CD-ROMs. All of these options have drawbacks. Installing a new hard drive in a notebook PC often requires expert assistance; purchasing a new PC can be rather expensive; and most external storage drives are costly, have a greater susceptibility to shock and vibration, and rely on an external power source and media. This drive is the best solution.
