Remember too that Windows 7 encrypts every sector - encryption of used space only was introduced with Windows 8. Encrypting 500GB will certainly take a while on a spinning drive.
Leveraging BitLocker Pre-Provisioning also enables used space only encryption - that makes it instantaneous to turn on for an empty drive.

The other alternative is to enable Bitlocker Pre-Provisioning from the Windows 8.0/8.1 ADK. Basically, it will encrypt the drive but leave the protectors "off", if you have ever "suspended" Bitlocker, it's similar. The Bitlocker is just "ON" and there is no need to go through the lengthy encryption phase. I've seen it work for Windows 7 SP1, and If you are using a product like MBAM, it should utilize the encrypted state of the drive and enable the protectors.

Just curious to hear what others have seen in terms of whole drive encryption. Does 12 hours to encrypt 500 GB seem excessive ? This is to encrypt the drive post Windows 7 install.
