Finding the max size of a tiered storage space - Windows Server 2022

As part of the work I have done in my homelab with tiered storage on Server 2022 storage spaces, here is a script I created that allows you to easily find the max size of a tiered storage space

Drop this in a .ps1 file and watch it go:

This script will allow you to easily Calculate the max size of a Tiered Storage Spaces

Virtual Disk when you add new a SSD or HDD.
