I can answer some of these and I will give you my opinion about the rest - since we don't know the primary use for this computer, type of data stored, how it is used, my opinion is based on "normal people" and how they use computers. Then you can decide how normal you are
and how it might apply.
I think you need to back up a little bit, regroup and do some more homework and decide what is better for you, based on how you use your computer. Windows 7 has built in (software) RAID support that works well - see
Link Removed - Invalid URL. But your motherboard offers hardware RAID too, which will work better, in most cases. You need to decide what you want to use, based on the primary use of that computer (serving music, gaming, office productivity, DVR, graphics editing, etc.). The Window 7 DVD (not CD
) will not likely have the specific drivers for your Gigabyte board's controllers. You will need to use the drivers from the motherboard's utilities disk, or better yet, the latest 64-bit Win7 drivers for your board from
Gigabyte's website.
That said, you say you are paranoid but you want to run RAID0. That is the most risky RAID configuration because with the data spanning both disks, if you lose one drive, you lose the whole array, and most likely all the data on it. And while it is true striped arrays can improve disk performance significantly, that does not always translate into
noticeable improvements in computer performance, not with today's machines running with lots of RAM and decent graphics cards.
If you are unhappy with your drive's and your computer's performance, I would be looking at freeing up at least 250Gb from your boot drive before adding more disk space. I recommend you move everything not Windows or hardware related off of C drive. Boot into Safe Mode and run
Disk Cleanup, then defrag C. Then consider leaving the boot drive for the OS and drivers only and use those monster 1Tb drives for your other stuff. Give Prefetch and Superfetch 3 or so days to learn you before deciding you need better drive performance. This assumes you have a decent supply of RAM too.
In any event - should you decide to create this RAID, regardless the method you use, I recommend option 3 from your list above. You might consider setting up a boot partition too - so Windows (or the page file) never get crowded out again.
