Special features of SSD drive encryption

The application supports encryption of SSD drives, hybrid SSHD drives, and drives with the Intel Smart Response feature. The application does not support encryption of drives with the Intel Rapid Start feature. Disable the Intel Rapid Start feature prior to encrypting such a drive.

Encryption of SSD drives has the following special features:

• If an SSD drive is new and contains no confidential data, enable encryption of only occupied space. This lets you overwrite the relevant drive sectors.
• If an SSD drive is in use and it has confidential data, select one of the following options:
  • Fully wipe the SSD drive (Secure Erase), install the operating system and run encryption of the SSD drive with the option to encrypt only occupied space enabled.
  • Run encryption of the SSD drive with the option to encrypt only occupied space disabled.

Encryption of an SSD drive requires 5-10 GB of free space. The free space requirements for storing encryption administration data are provided in the table below.
