Storage Spaces - Stay or move to a new solution?

I’m at a crossroads with my Windows Storage Space Parity volume. I have been using this solution for mostly a media vault for years (2016) with little issues aside from slow writes. A few years ago I upgraded to Server 2019 and new hardware where I read more on how to properly set up a parity storage space in PowerShell. This seemed to resolve my write issue for a while but for some reason it is back.
