Full disk encryption (FDE) systems use strong encryption algorithms to automatically protect all data stored on the hard drives of PCs and laptop computers. FDE’s biggest advantage is that there’s no room for error if users don’t abide by encryption policies. Hardware encryption will continue to evolve, and future choices will appear in other device subsystems, such as CPUs or supporting chip sets. FES is more compute-intensive than FDE, leading to PC performance hits of 15 percent to 20 percent, versus just 3 percent or 4 percent.”]
