the "winraid" indeed is software raid. And yes it's generally inferior
to linux native raid for RAID0; this has to do with the on disk format.
Depending on the disk geometry (odds of hitting the "wrong" geometry are
like 50%) and where you put the partition exactly, you can very well end
up with a RAID0 stripe boundary being in the middle of a 4Kb block of
the filesystem. This results that when the kernel does 1 4Kb IO, the
hardware needs 2 IO's in practice, including 2 head seeks. This is
actually measurable performance impact. Again this effect depends
largely on how the start of the partition aligns with the stripes, which
in turn depends on the geometry.

Fwiw in linux this raid is supported by dmraid, but the installer side
of things isn't quite there yet, nor is the bootloader side.
