Truecrypt and RAID 1

I have used Truecrypt for full system encryption on 2 laptops. I am very happy with that setup. Recently purchased desktop with RAID 1 setup - 2 hard drives using Intel Matrix Storage Technology and RAID controllers in Windows 7.

I would prefer to do full system encryption on the desktop computer but am not sure if this would work appropriately in RAID 1 protocol. In other words, not sure if the RAID functionality boots before Truecrypt (or perhaps some other challenge). As a backup plan, I could always mount a volume to store the most important files. Any input would be greatly appreciated.

Many thanks!

If I am understanding you right, the RAID controller is integrated into motherboard. If so, you should be fine for any full-disk encryption, since they won't load the necessary decryption keys until after they have access the hard drive (at which point the storage drivers must have already been loaded).

I don't know if the RAID controller is integrated in the motherboard. I can access a software application called "Intel Matrix Storage Technology" which allows me to manage the RAID system. Is there an easy way to determine if the RAID control is hardware (motherboard) or software mediated?

The Intel Matrix drivers are for Intel chipset based controllers. They are not software-only RAID (like LVM and such), so you should be fine.
