    Using Intel 300 With Full Disk Software Encryption

    tim10

      I'm looking to upgrade my system drive to an SSD drive and am interested in the Intel 330.  From my understanding, the 330 has hardware encryption, but as my BIOS doesn't allow for a Hard Drive password I want to use full disk software encryption (Truecrypt) instead.

       

      After reading up on different SSD's, some people are saying that the Intel SSD wouldn't be a recommended choice for a software encrypted drive due to the fact that they use SandForce controllers which rely on compression for performance.  And as the encrypted data can't be compressed they're recommending using SSD's that don't rely on compression, such as the Crucial M4 (which uses a Marvell controller) or the Samsung 830 (which uses Samsungs own controller).

       

      My processor doesn't support hardware accelerated AES (AES-NI), so I accept that I'm going to take a bit of a hit in performance by using a software encrypted drive, but how much of a performance difference will there realistically be between using an SSD with a SandForce controller and one with a non-Sandforce controller?
