It occurs to me, if self-encryption becomes a common feature in drives, perhaps one of the banes of a quick boot-up (anti-virus checks) could be eliminated during some or all of the boot-up phase? TPMs are also working their way into popularity (IDC figures a 90% attachment rate by 2010), which would offer a more complete chain of trust to complement self-encrypting drives. If it could be trusted that no modifications have occurred to the drive since the last boot, couldn't a lot of scanning be eliminated, with a focus only on newly added content?
If well-coordinated with AV software, I wonder if this will open the door to snappier boot times on Windows platforms?
