> This is a no brainer. I have yet to notice any real performance hit for enabling full disk encryption. Just enable it, make sure to have a long/strong password, and make sure your computer actually locks when you close the lid.
I have confirmed, using dtrace, that OS X uses Intel's AES-NI instructions to accelerate encrypted disks. I found no performance decrease for batch file copies. I did not test small files nor seeking. I should run more benchmarks now that I have an SSD. Perhaps the CPU is now the bottleneck.
