A PenDrives is a great, convenient data storage device if you need storage you can remove from your machine and keep outside of your computer. Usually PenDrivess employ flash memory sticks to provide file space, but that can be costly. Pocketec offers datastor external drives, which employ harddisk spinning technology, for a much more affordable approach to massive storage capacities, but each model from the ultra, pro or mini series can fit in the palm of your hand, so you don't have to sacrifice the tiny footprint a pen or keychain drive provides. Pen Drive Tips The datastor models that we offer function just like traditional pen and jump drives, but they come in 20gb, 40gb, 80gb and even 100gb configurations. Better yet - these hard drives are compatible with multiple platforms, so you can use them with your windows, macintosh and linux computers. Most operating systems will let these disks work as plug and play, so you don't have to install an additional driver, and most computers will power these drives via the usb cable, so you don't have to deal with a costly battery or a bulky power adaptor. Maintaining data on a network consisting of several different computers with different specifications has never been easier.
