Hey there, I started to like FileVault 2 for my Mac. Speed When I formatted my external disk I was prompted whether I wanted to encrypt that disk as well and I turned it on. However it seems that writing to this drive is now super slow, copying a 30GB folder now takes more than an hour (USB3, took a few minutes before). Does anyone experience this well? I'll add some before/after write speed tests later. Security What does actually happen to an encrypted disk? Can I access my data on other Macs? What if it gets stolen, is it as secure as the disk within my Macbook or can someone still access the data using a Windows machine or something similar? Thanks guys!
