Data Protection - a feature that is of high significance to most is having the ability to secure sensitive data and files. It is not difficult nowadays to find hardware of this nature which comes with such desirable features as password protection, automatic backup options, hardware encryption and built-in diagnostics. Back-up devises without a means to secure the data are still commonly available, these might be acceptable for simple back-up needs at home, but should really be avoided for business purposes. For the highest security, a USB external hard drive might well come with a security slot which allows you to bind the device in place, which prevents unauthorized removal.
