File security is usually associated with corporate data. However, if you're like me you have quite a bit of valuable personal data on your Mac. I have accumulated all my old tax returns, bank records, receipts and PIN numbers on my computer. I have been using Knox to maintain a set of secure folders for my files. It works great and is pretty easy to use. It was so useful that I purchased a license. However, now that I have plenty of disk space in the Mac Pro (vs. my G4 Powerbook; 160GB) I was thinking about switching to Apple FileVault. I haven't found much negative feedback and it does not involve a separate action to mount the secure volume. This guy seems to think it is the shiznit.
