Here is a Powershell script to monitor the health of RAID arrays on Windows from https://gist.github.com/schakko at https://gist.github.com/schakko/4713248
I tested it on a Windows 10 software raid and a Dell PERC H700 hardware raid on Server 2016. Worked well. We use MegaRaid for notifications.
I'm reproducing it here just in case the Gist goes away, like the target on the accepted answer https://serverfault.com/a/150089/2985
The "Fehlerfre" and "Fehlerhaf" in the script are German translations for result codes.
# A simple PowerShell script for retrieving the RAID status of volumes with help of diskpart.
# The nicer solution would be using WMI (which does not contain the RAID status in the Status field of Win32_DiskDrive, Win32_LogicalDisk or Win32_Volume for unknown reason)
# or using the new PowerShell API introduced with Windows 8 (wrong target system as our customer uses a Windows 7 architecture).
#
# diskpart requires administrative privileges so this script must be executed under an administrative account if it is executed standalone.
# check_mk has this privileges and therefore this script must only be copied to your check_mk/plugins directory and you are done.

This version from https://gist.github.com/LionRelaxe also emails error results (https://gist.github.com/schakko/4713248#gistcomment-2256715)
