I'm just curious as to how many Linux users here bother with it. I have
opal2 encryption on my storage but find the process of enabling it on
Linux way too complicated to bother, and I know that software encryption
will slow down the storage heavily. Yes, it's good for security, but I'm
wondering if anyone actually uses it and why.

Yes, I use it. It was easy to set up, just a checkbox in the installer
and entering the passphrase. I do it because I don't want my data to be
readable when someone nicks my laptop / computer. The performance impact
is hardly noticeable, if at all. It's all hardware accelerated anyway on
any modern CPU, and more often than not the hard drive is the bottle
neck, not the encryption.

The real important thing about security is to know against who you need
to be protected. You are afraid your computer can be stolen, so you have
to be protected against that. For my part, I don't and I have nothing
secret on it. But, if I have an issue, I need to be able to recover the
easiest way possible. And if my system is encrypted, it can be
difficult, so I don't. And I know: if my government want to access my
computer, I can't fight, so I don't try. Would I be a journalist or
something like that, I could try to have better protection against it.

Mind you: I'm not saying I have no backup. I back up the most important
things but it doesn't mean I wouldn't care about less important things.
I wouldn't have big issues, but if I could avoid it, it would be fine.

So, I'm protected against disasters: if my home burn when I'm not there,
I can get the most important data back. And I'm protected against
Internet script kiddies. Because I know that if government want to fight
me, I can't compete, or it would be, at least, more difficult to manage
and I know that my government want to fight me. I mean: I'm not a
target, I don't mean they try to target everyone to see and I'm not one
of them.
