I've got a server running windows 2008R2. The hardware controller can only do Raid 1 or 0 and it's hotswappable. I have 4 drives (hot swappable hardware), each pair is mirrored (raid 1). I'd like to do raid 10 but the hardware can't.
So, I'm wondering if stripe (raid 0) in software across the 2 mirrored pairs (in hardware) would give me a disk io performance increase. Our big issue is disk IO, we have extra CPU clock cycles to spare, but would like to not have 2 virtual drives but instead one striped volume.
Would there be a performance increase using software striping? Can this be configured during install?
