Both my OCZ Vertex 2 240GB (with it's SF-1200 series controller) and my Intel SSD 320 support full disk AES encryption. I would like to use BitLocker on this laptop to prevent data theft, but BitLocker destroys performance on SandForce drives like the Vertex 2, and significantly impacts performance on drives like Intel's because the CPU is being used for encryption (affecting things like DMA).
Given that these drives already are doing hardware AES encryption of the data on the disk, how can I take advantage of that to prevent someone from stealing data off my laptop?

At the moment, only the Intel 320 SSD supports this, as described here:
SandForce drives, such as the Vertex 2, do encrypt the full drive contents, but do not provide the sort of security you are looking for. At the moment, the encryption feature is only useful for a quick secure erase of the drive.
