Hi !
Some say on the internet that an encrypting disk takes resources (processor…) and slows down system.
But you can see on Youtube that with a special USB key could override the password request and access the user’s account.
Having an encrypting disk would be the only protection.
I still install Linux with “LVM crypted”.
Actually I testing an installation without LVM and encrypting on my entry-level computer…
For now I just noticed slowdown as disappeared on TV program broadcaster’s website.
