For details of DE supported environments, see KB79422 - Supported platforms for Drive Encryption 7.x. SummaryIf you're familiar with DE, you know that initial encryption of your entire drive can take 3–6 hours. This period depends on the size, speed of the drive, and CPU.
In DE 7.1.0 and later, enhancements were made to the Offline Activation feature with two new capabilities that enable you to perform the following actions:
When both of the above capabilities are used together, you can encrypt a new drive in minutes. As you use new sectors on the drive, these sectors are encrypted on the fly.
For example, on a new Dell latitude E6410 laptop with a fresh Windows image, regular encryption would take 5.93 hours. In contrast, Fast Initial Encryption can complete in just 4.53 minutes. NOTE: To review performance data for DE 7.1, see KB77844 - Performance data for the new Fast Initial Encryption feature (Used Sector Only). For scenarios where you pay IT by the hour, this feature can result in savings of about $125 per laptop, assuming $25 per hour, with no loss in security posture. For more technical information about this new capability, see KB79784 - FAQs for Drive Encryption 7.x. NOTE: Fast Initial Encryption is available only as a part of the offline activation process. The offline activation option is Skip Unused Sectors.
For installation advice, see your respective DE Best Practices Guide and Product Guide. For product documents, go to the Product Documentation portal.
