When data confidentiality is required, the drive uses hardware in the US Government AES-validated Marvell controller to provide secure 256-bit full-drive encryption.
In addition 128 bit AES encryption provides data protection and in particular can be used to rapidly erase the encryption key so the drive can be repurposed without concern about the old data being accessible.
Dotcom adds in that although other services don't have a one-click encryption option built into their interface, the likes of Google Drive allow you to upload encrypted, password-protected files.
Iomega prides itself on providing total solutions, which is why all of the new Iomega USB 3.0 eGo Portable Hard Drives come complete out of the box with 256-bit hardware encryption built-in (PC only), as well as the cables required to enjoy your drive right away, whether your desktop or laptop has USB 2.0 or USB 3.0 ports.
