Brad is planning to build a Windows 8.1 rig and is curious as to how Windows 8 will handle the SSD drive and if Windows eDrive will be good encryption. Leo says it will work just fine. And you really do need to encrypt anything you put on an SSD drive because it doesn't really delete everything. But encryption software from Microsoft may have a back door on it for the Feds. But if that's not your worry, then Windows E will work great for basic protection. But if you're really paranoid and concerned, then Leo advises using TrueCrypt.
