Data, our computers can be filled with hundreds of gigs of music, photos, and files. If for some unforeseen incident the hard drive crashes, data recovery of such files can be costly. It is important to always back up your data. Portable hard drives are a solution for many in backing up data, or to transfer data. MY Passport elite by Western Digital is a fine choice for either backing up data, or transferring data. The portable hard drives come in 250GB and 320GB choices, and pretty much perform identically. The bundled software that comes with the hard drive is pretty cool also. MioNet lets you remotely access other computers that have been installed with the software. MioNet really makes filesharing easy, with the many options is has. The rest of the software that comes with the hard drives is the standard stuff we usually see with the other hard drives. These things are quick.
