X-MEM External Hard Drive
 

Whether you use a desktop or laptop computer, there is one thing that will
certainly happen, one day you will run out of hard disk space. For those
who need to easily add more hard disk space to their computer or simply want
to be able to transport large amounts of data from one machine to another,
there is now an easy way to solve your problem. External hard drives have
been available for a long time. Based on SCSI, Parallel, USB, or FireWire,
they provide an external case for a standard hard drive with connectors for
the interface and power. One of the latest offerings from Targus is the
X-MeM External HDD.
