Plenty of SSDs implement strong encryption, and there's an entire standard API for it. Why waste cpu on tasks your hardware already does?

Bitlocker supports on drive hardware encryption, and I'd be surprised if other major file systems didn't.

If I recall, it's a FIPS requirement for data at rest now.

Because the storage hardware might be loyal to someone who is not the owner of the data.

Because the hardware cannot be trusted to do it correctly. IIRC Bitlocker stopped relying on it for this reason.
