What performance impact should be expected when PGP Whole Disk Encryption is in use?
Once the hard drive is encrypted, the performance impact of PGP Whole Disk Encryption is negligible. Some users may notice a performance impact during the initial encryption process; however, this is a one-time-only event during which all current-generation PCs will perform normally, although disk-intensive computing processes may take slightly longer. The initial encryption process can be suspended at any time to complete time-sensitive or disk-intensive tasks.
