Quick question here,

I just wanted to know if it was possible to do RAID 0 on the BOOT drive for Win 7 Pro via the Windows Software RAID. I know that mirroring is possible, but can you also do stripped set ups? From what I have read, it is not possible to do this with Windows 7/Server 08 R2.

Oh, the answer to your question is yes. Setup the RAID volume in the BIOS.....

^+1

The one that came with mine is intel matrix storage manager, but be the same on yours. Its really easy but it add a good 7ish seconds to your boot up, its annoying. But i recently figured out you can skip it by pressing esc when it comes up lol.

^Yes, I'm aware of setting up RAID via BIOS/RAID card, however I would like to know if it is possible to do software RAID via Windows 7 on the boot drive. I know how to do this for non-boot drives, and I know it is possible to do RAID1 on the boot drive, but I want to know if it is possible to do RAID 0 on the boot drive via Win 7.

This is what I'm talking about: http://www.techimo.com/articles/index.pl?photo=149

The answer is no. You can not use Windows own software RAID with level 0 on the boot/system partition. That is because to access the RAIDed information the OS has to load a driver (called ftdisk.sys in earlier versions, do not know if it still does) and to load that driver it has to access the disk.

So it is a catch 22, and can not be done. RAID 1 will work, since all information is on both disks so the operating system can boot.

Linux can have RAID 0 on its own boot device? I wonder how it can load the RAID0-driver in the first place?

^ Yes. You can create a RAID0 array for the boot device during the installation via Live CD or Installation DVD. Linux has been able to do these kind of things for a while now. It's quite annoying Microsoft hasn't adopted this stuff yet.
