By the way HB, I'm still using the controller you suggested in a thread a long time ago... and I'm considering wiping both drives so I can use the full RAID capability. Do you think it's worth it?
Let me make sure I understand you correctly...
You currently do not have RAID enabled; you've been using the controller simply as a SATA interface? If that's the case, I would recommend you wipe the drives clean, setup RAID0, and then use that as your boot drive. (You won't notice much performance increase if you use it as a secondary storage device for games, audio, etc. unless you
really access it frequently.)
The disadvantage is that you'll have to reinstall your OS, during which you'll need to load "third-party drivers" for the storage controller for the OS setup to install to it.
Oh, and I can't remember the exact controller I recommended. I believe it's the one I use... but to be sure, my recommendation only stands for the SiI3114R chipset.
