I'm interested in a hardware based full disk encryption solution for a laptop. I've never really researched them before, so I'm not sure what to expect. (This is not a shopping list question).
I'm finding a fair amount of related material for encrypted hard drives. For example, an Encrypted SSD that operates independently of the platform (like a Dell laptop) or the operating system (like Windows). That is, the drive displays a UI during the boot sequence and the drive prompts for a password.
I'm not finding integrated offerings from laptop manufacturers like Dell and HP. Or my search skills are performing poorly. For example, my search for encrypted hard drive site:dell.com did not return one laptop model. But I expected to see a search result like Series XXX with Full Disk Encryption.
Question: is it normal or expected that I'm not finding integrated solutions from laptop manufactures? Or is an encrypted drive normally just an upgrade to a laptop, similar to upgrading to a larger drive?
Related: the reason I want an integrated, hardware based solution is I want to multi-boot the laptop with both BSD, Linux and Windows. So I don't want contention among operating systems for control of the boot loader, I want to be able to read other partitions, etc.
Here's a related question, and the fellow asking seems to be having trouble sorting things out, too: Is there anyone using hardware encrypted HDD on their laptops?.
