Hardware Encryption
Since DbDefence version 2.10, we have included support for AES Instruction Sets on modern CPUs. This speeds up the encryption process, making it five to eight times faster. However, on most systems, this feature does not increase load times by much. This feature is primarily for extensive database systems with extremely large databases. You can see if your CPU supports the feature by executing the dbd_status command.
Advanced Encryption
Standard (AES) Instruction Set is an extension of the x86
instruction set architecture for microprocessors from Intel and
AMD. Intel proposed this instruction set in March 2008. The purpose
of the instruction set is to improve the speed of applications
performing encryption and decryption using the Advanced Encryption
Standard (AES).
List of supported CPUs from Wikipedia

- Intel Gulftown processors.
- Intel Clarkdale processors (except Core i3).
- Intel Arrandale processors (except Core i3, Core i5-4XXM).

Bridge processors
- Desktop: all except Core i3.
- Mobile: all Core i7. Though the Intel web pages originally listed the 2630QM and 2635QM as not supporting it, those web pages have been updated to indicate that they do. Several vendors have shipped BIOS configurations with the extension disabled, requiring a BIOS update to fix.
