I own several WD portable drives and can highly recommend them. Their portability also makes them great for providing more storage for laptop owners who've filled their internal drives, but aren't ready for a system upgrade quite yet. They can store and transport a large quantity of data quickly and easily - just one USB cable will transfer the data and power the drive, and once complete, they're small enough to slip into a jacket or even trouser pocket. This is why portable drives are so useful. Summary Backing up your data, whether it's photos, videos, music or plain old documents, is critically important, and a crucial part of the process is transporting the backup to a different location.
