Full Disk Encryption vs Encrypt whats in use

I have a question about Full Disk Encryption vs Encrypt whats in use.  I recently tested the "Encrypt whats in use" which took about 4 hours to encrypt on my test PC.  But i was left wondering if the disk continues to encrypt as it grows or not?  I figure Full Disk encryption will do exactly that.  Encypt the used and unused space no matter what.  But the other setting has me worried that it is lacking in coverage.  Otherwise why have to two different options?

  • Thanks for the reply.  Good information there.

    Yeah my test PC had several programs from my company as well as it was PC that someone used for a period of time before switching over to a laptop.

    Im not worried about the speed honestly.  I know there are several factors involved there.  I was mainly concerned about the difference between the two types of encryption.  

    So based on my environment and how I am going to use the product it sounds like full disk encryption is what I need.  The laptops that are going to receive this encryption have been in use for a while so data on them has "come and gone" so to speak.  Potentially leaving behind information on what is now unused sectors of the Hard Drive. 

    Im glad I raised this question because I was simply going to stick with FIE method, but now I think I will go Full Disk.

    Thanks a million.
