The free plan (IDrive Basic) includes 2 GB and the iDrive Pro includes 150 GB for$4.95 ($0.03/GB). IDrive Pro for Business starts at $9.95 for 50 GB and goes up to 500 GB for $49.95.

The IDrive client in fact consists of two parts, IDrive Classic and IDrive Explorer. The Classic interface is where you back your documents up, though many reviewers seem to experience some uneasiness with it. The Explorer portion of the software is much like Windows Explorer with folder trees and only allows file restoration functions. Although you can restore files from the Classic interface, only IDrive Explorer allows you to restore files through a drag-and-drop process.
