Software raid (implemented in os, not the fakeraid/softraid chip on motherboards) in this case is better because it can use as much memory as it needs and also since it is part of the OS it can receive additional information on what kind of workload OS wants from it, i.e. readahead or not and how much. Hardware raid generally doesn't know about those things and tries to infer them so it can't optimize fully.

Sort of, I’d have no issue with software RAID. VMWare however has exactly ZERO software raid options so on servers you are limited to HyperV it seems.

  Or the myriad of Linux based options

    Let me know when they approach VMWare’s market share, texture, third party acceptance, and support. I’ll switch all our servers over right away.

      Xen/KVM market share probably dwarfs VMware if you look at total systems. It's what a lot of the large cloud providers use (AWS/GCE at least). I assume Azure uses HyperV, and also that a lot of shops are using it because it's the supported MS product. Our company has VMware and HyperV deployments for just that reason (Office IT has their own MS cluster, systems uses a VMware cluster we admin. Yes, it's silly, but does illustrate a point).
