I have a laptop with an Intel CPU (with AES-NI) and a Samsung 840 EVO (supports AES-NI) with TrueCrypt Full Disk Encryption and Windows 7 already loaded.  My questions are:

1) [MAIN QUESTION] Will enabling the SSD's encryption functionality (by enabling the BIOS hard drive password)  have any effect on the performance of the SSD Drive that is already encrypted with TrueCrypt (Full Disk)?

2) Would this be redundant to have both the SSD AES encryption enabled and TrueCrypt enabled?  My understanding is that onboard SSD encryption (key storage method and location unknown) may not be as secure TrueCrypt.

3) If I do enable the SSD/BIOS encryption, can I do this without losing the current contents of the SSD Drive since I already have the OS installed and TrueCrypt active?
