Re: [H] Truecrypt 5.0 now does system (boot) drive encryption and works with OSX
If you run TC's benchmark during the container creation process you can see what kind of hit you're going to take. Notice it or not, depending on what cipher if you're chaining them together. there is a performance hit. My assumption is it's not drive speed but CPU so the faster the CPU(s), the less you'll notice. Combining TwoFish + AES (for example) WILL cause a performance hit.

Re: [H] Truecrypt 5.0 now does system (boot) drive encryption and works with OSX
If you use keyfile(s) then passwords are not an issue. You just issue your users a small capacity thumbdrive encrypted by TC w/ password to protect the keyfile(s) on it. Or if you are serious pick up some IronKeys and use them to store keyfile(s). Don't know how this affects the new TC version if it's pre-boot security but works great post-boot to mount my secure documents partition. Yes you can/should backup but there some data that is too large for backup yet you want stored securely (temp files like downloads) or windows goes whacky between backups you rather not loose the changed data. I have had this happen under DriveCrypt previous versions of TC where your entire container/partition is useless due to corruption in the beginning of the container. On an unencrypted partition there is always the ability to do sector-by-sector. Even windows EFS worst you loose is 1 file, so TC the like to be as recoverable IMHO.

Now that's cool news! Truecrypt is good stuff. I have yet to see data recovery program to salvage encrypted partitions (assuming you had the cipher). Doesn't make me real comfortable if a single bad sector would leave my data inaccessible.

Likely no more than EFS does but would depend on the type of encryption used. Ben Ruset wrote: I wonder how much overhead encrypting the system partition puts on the system.
