The MiniStation HD-PXTU2 is designed to replace the MiniStation HD-PXU2 adding the Buffalo Tools Software Suite. Traveling is hard on an external hard drive and whether it is across the street or across the ocean, you need a compact, lightweight storage solution that is equipped to handle the rigors of the road. The MiniStation touts a rubberized chassis and BumperBody shock absorbers that surround the hard drive inside, defending it from damage due to an incidental knock or a hard drop. The MiniStation also protects your data from unwanted access by safeguarding your digital assets with a 256 Bit AES hardware encryption that, uniquely, can be turn on or off. All of your photos, music and personal files stored on the MiniStation are automatically protected with the highest available data encryption. Plus, with the intergraded E-Z Logon feature you only have to enter your password once on a trusted PC.
