I read the wikipedia article and few others, however I still don't have some things clear. The main question would be what does hardware full disk encryption imply for the user, however I have more specific questions related:
- Can I use the Samsung 840 EVO with an external 2.5" USB 3.0 case?
- If so, would I be able to change it from one case to another or to the motherboard?
- If yes to both of the above, what is the encryption actually doing? Stopping a hardware read/write while the disk pcb is off? That doesn't sound like very protecting. On the other hand, if it was no to any of the above, I don't see many end-user (with low to normal security needs) advantages.
My questions come specifically from this part from the Wikipedia's article:
Authentication on power up of the drive must still take place within the CPU via either a software pre-boot authentication environment (i.e., with a software-based full disk encryption component - hybrid full disk encryption) or with a BIOS password.
