software RAID capability is Nice in Windows 2003

I have years of hands-on experience with Soltice Disk Suite under Solaris and LVM or alike under Linux. Trying hard to stay open-minded with ears up over the years, I don't think I heard a beep about the nice software RAID capability inside Windows 2003. Don't have figures for reliability/performance and such in the self-training kit book for 70-290. That aside, I was pleasantly surprised and truly impressed by the wizard driven RAID capability. Using Disk Management ( diskmgmt.msc), one can convert a basic disk to a dynamic disk, then to create a new volume by extending (spanning), stripping [RAID 0], mirroring [RAID 1], stripping with parity [RAID 5].
