Many today SSD and some magnetic disks have AES-128/256 encryption
builtin.
If BIOS supports it, it ask for password then send it to hard disk after
which it decodes it's AES key so it start to work.
No software crypto overhead, everything fine.
My question - how secure it really is.
One extremity is to assume it is certainly well done.
Another - that there are encryption at all, just simple password check.
Both are possible as there is no way to check.
I want your opinions. Software encryption would make quite a bit overhead
for my setup.
