How do I set up Raid 0 on Windows 7 on a Gigabyte Motherboard

Not sure what you are trying to accomplish here. RAID 1 will give you redundancy (i.e. fail over in case first drives fails), in windows essentially you will configure these two drives as mirrored. If you are creating a volume strip, you are virtually putting two drives to look like one to OS hence creating one big drive. The performance of two stiped drives compared to one large drive is not better, its probably worse unless you used some high caching mechanism.

Well I was told that if you buy two hard drives and put them in a Raid 0 setup, you will get the performance double of 7200rpm.  How should I set up these drives for the best performance, I am not worried about them failing.

I am afraid , I don't believe thats true. 7200 RPM is spindle speed of hard drives which contributes towards head accessing the megnatic media on the drive. If your information is stored on the second drive, to access that information, the second drive will still move its own speed to get to your data , sptriping might make it a bit longer though because it might be the first drive who has FAT (the table of contents). Once again, there is a possibility of speed performance gain over a single drive when your drive start to fill-up, single drive might take it longer to access data, also your caching mechnism might improve performance a bit but not significant.

well I would like other opinions please from people who know what I am talking about.

First, google experts exchange and look for all the horror stories from people who install windows using software-based RAID.  It works great, until there is a hiccup, and a lot of people end up losing everything.

Secondly, you need to configure dynamic disks which are NOT available in standard/home editions of win7.

I would think this plan over, and if you really wanted to do RAID0 for performance reasons, then get a decent RAID controller and go RAID1, which will generally provide better performance than just a single disk drive, and you are protected in event of a drive failure.   Later on, you can buy 2 more disks and go RAID10.

so can i just use the drive as a backup drive for stuff until i figure out what to do?  i can create the partition in disk management in windows 7.  i can just keep all of my recorded video from WMC on there.  thanks

thank you!
