I have an external HD I use for extra storage and it's encrypted, every time I plug it in OSX asks me for the password to be able to read and mount it. In my mind, this makes sense, the disk is worthless without the password if anybody gets their hands on it.
My MacBook disk however never asks me for the password, yet it's also encrypted with FileVault. When I reboot or log off/in, it just loads. I'm probably wrong so correct me on this, but it seems that I'm gaining no extra protection beyond my user password.
If someone steals my computer, if they have my account password they have access to the disk whether or not I've encrypted it. So what's the advantage of using FileVault in this case ?
Dupe vote update: The linked question explains how it loads without asking for the password, but doesn't answer the question as to what's the advantage of using FileVault if all I need is my user password to access the disk ?
