    I am interested in encrypting my whole home directory in the intrest of security but the only thing im worried about is the possible drawbacks/downfalls to doing this (if there are any)?

    Do you have filevault enabled and how do you find it?
    Does it slow down your system at all?
    Will it decrease the battery life of a macbook pro by much?

    Doesn't slow down the system, but it does take a bit longer to shut down the computer because it needs to recover file space. The vast majority of times (95%) I just put my computer to sleep by closing the lid.

    Not sure on the battery life, but I usually get 3 hours out of my new MacBook. A little less than what other users get, so maybe it does decrease battery life.

    I turned FileVault on recently on my MBP and to be honest I haven't noticed any real difference in speed at all. Pleasantly surprised really, I expected a noticeable difference in overall speed. I'm definitely happier that my home directory is protected though.

    I've been using filevault for months and haven't noticed any difference in speed or battery life.
