A Portable hard drive is one of the best available solutions in contemporary times for storing high volumes of data and keeping it secure.

In a Floppy disk there is no guarantee of data retention and the amount of data stored is negligible, as compared to a portable storage device.

The portable storage device is considered to be a better option than a CD (700 MB) or a DVD (4 GB or 8 in case of a dual layer DVD), as one does not need a writer to copy data on it.

These drives are a viable option compared to thumb drives/pen drives. A thumb drive can store up to 2 GB of data, which is much less compared to the portable drives. Also, carrying a portable drive is not a problem at all, given its sleek and compact design.

The potential of a portable drive to store high quantity (20, 40, 60, 80, 120 GB) of data is also an advantage.

The portable storage drives available in the market today are plug and play devices. One does not need anything else to run it. Just plug the device to a PC/notebook via a USB cable and you are on. The devices are USB 1.0 and 2.0 compatible.

It is also very easy to copy files from a PC/notebook to a portable storage device. Just copy the files from the former and paste it in the device. You can also keep the device attached to the PC and run files from it.

Some of the popular brand portable storage devices available in the market include LaCie, Iomega, Fujitsu, and SeaGate among others.
