I think for average users, they may not feel the performance hit of software FDE most of the time, but everyone will experience it sometime. Few example of this is: 1) If a user is working with large files (i.e. excel, pictures), the constant data encryption/decription that occurs with the swap space on the drive will be a performance hit. 2) Same thing goes when the hard drive is defragged. 3) Lastly, when uninstalling the software fde, the decription process will take a while.
