What software should I use to encrypt my hard drive? [closed]

I am currently running Windows 7 RC x64 on my home system, and am interested in encrypting my hard drive. I've heard good things about TrueCrypt, but am curious what other folks might suggest. I primarily use my system for software development, so am concerned about any system performance degradation that encryption might introduce.


TrueCrypt is the de facto standard.

Free open-source disk encryption software for Windows Vista/XP, Mac OS X, and Linux.

The following features are planned to be implemented in future versions:

Full support for Windows 7


Windows 7 has full disk encryption built in with Bitlocker. You will have it available in the RC but come RTM it will only be available in the Enterpise and Ultimate editions.


As you mentioned, there's TrueCrypt.

There's also PGP Whole Disk Encryption.

If you purchase Windows 7 Ultimate, you'll also have BitLocker built in, which is one of the few compelling features of Ultimate.
