> First I've heard of the deprecation The option to create software RAID 5 from disk management has been removed already from Windows 10 desktop (you are supposed to use windows storage space, but as I mentioned, it really sucks for RAID 5). I am sure Windows Server will follow at one point. > I recall during setup my 14tb drives were not exactly the same size, and I found some way around it by just creating a volume of the same size as the first Yeah you can create a RAID volume of the min size across all disks. And then you can probably even create another RAID volume with the rumps of the larger disks. But you end up with multiple volumes. More modern solutions (synology, windows storage space) allow you to create a single volume that spans all disks and utilises their whole capacity. Synology by creating a bunch of RAID 5 volumes behind the scene, then joining them with a RAID 0-like (don't think it's RAID, just some sort of virtual volume). Windows storage space by writing strips of your data randomly across all your disks (the number of columns is decorrelated from the number of disks), ensuring that every strip is at most on one disk for single parity.
