Relocate your "home folder" to your On-The-Go Pro and have your files with you at home, at work or on the road without the need to synchronize your machines.
Laptop Owners
Clone your current internal SATA hard drive in your laptop to the new drive. Then install the new, larger drive in your laptop and keep the smaller drive in your On-The-Go for additional storage space.
iTunes Aficionados
Keep a copy of your iTunes library on your external drive to play on multiple machines.
Add additional storage to your XBox 360 or PS3 game console to store music, media, and other downloads. PS3 even includes a backup utility to protect your internal drive's data.
For Everyone
Have the peace of mind of a complete backup plan. Create a bootable clone of your hard drive at regular intervals so if your computer goes down, your productivity doesn't go down with it. Boot to another computer and keep on working!
