When it comes to taking lots of digital photos and video both amateurs and pros alike often need a place to archive all of that video to free up space on their memory cards. You can lug a notebook along with you to do the archiving, but a less bulky way would be to use a device like the NEXTO eXtreme portable hard drive.
The NEXTO eXtreme hard drive is a portable device that has both a memory card reader and a USB port that allows direct connections to cameras of all types. The drive can be had with storage capacities ranging from 160GB to 500GB. The drives can be expanded all the way to 2TB of storage.
