There is no way that using a fake RAID set of drivers and a completely incompatible and more complex on-disk RAID format is going to increase performance in any way. There's a reason why that hasn't been done on any system in the past - because it's stupid and fake RAID drivers are notoriously buggy and require support from cloning and other low level software that gets used. Yer, you're not an expert, or appear to know anything about hardware.
