stefeman Posted February 17, 2013 Share Posted February 17, 2013 Been doing some research on this and still haven't found a definitive answer to these questions: Performance - will it be significantly reduced? Is the drive's life expectancy shortened by encryption? If so by how many years? If i apply full disk encryption (truecrypt) and the performance after encryption would be bad, would full disk decryption fix the issue and revert the performance back to it's original state as it was before the encryption? I also noticed this message on another forum: Using encryption on a Sandforce based drive would be a BIG no-no as ALL data on the drive would effectively be in a compressed state and therefore eliminate the possibility of the Sandforce controller using it's compression algorithms to promote top speeds. Corsair Force 3 uses Sandforce right? So am i able to safely test the encryption and speeds after the encryption, and if i don't like it, i could always decrypt the drive and attain original speeds? Or would i lose those original speeds forever after the encryption? Any advice / discussion is much appreciated. Link to comment Share on other sites More sharing options...

Toasted Posted February 18, 2013 Share Posted February 18, 2013 Yes, encrypting the drive will cause the performance to drop. The life expectancy cannot be estimated as it depends on how you use the drive. I'm not sure if a decryption would restore the speeds. But it probably will. Yes, the Force 3 series SSDs have the Sandforce controller. You can restore the drive's performance by secure erasing the drive with Parted Magic.

sambo1 Posted February 19, 2013 Share Posted February 19, 2013 The life expectancy cannot be estimated as it depends on how you use the drive. This is true but not the full story. All other things being equal an SSD that is encrypted will have a shorter life expectancy than one that is not encrypted. That is just a fact. How much shorter depends on many factors. But the fact that it is going to be shorter is not disputable. And yes, using encryption on a sandforce controller is plain silly because one defeats the entire purpose of having the compression on the sandforce, which is the main reason to get the drive.
