[OSX-Users] Re: Mac disk encryption

[Steve Harris]

It was true in File Vault 1, but not anymore.

If you have spinning rust disks, or slow CPUs it does slow down the machine a fair bit, as it has to write more data to safe files (for e.g.), and obviously taxes the CPU a bit more.

I've run FileVault on MacBook Pros from about 2007, and it was a noticeable, but acceptable burden. I worked for a high security company, so it wasn’t optional.
