Ouch.

What you really need to look for is IOPS/latency, not bandwidth.  I
rarely see upwards of 60MByte/s through NTFS unless very large files are
involved (and only then I've ever seen it surpass the SATA barrier of
~550MByte/s and not by much), but the QVO is better suited for warm
storage / backups and has pretty long response times and the low IOPS
that come with it when you fill the queue.  The NVMe on the other hand
mostly registers below 1ms where the former SATA disk (a WD Blue) was
all over the map up to almost 300ms at times and around 3…10ms average
under load.

That system is at its official max. configuration of 32GiB (4x8GiB ECC).
But as I said, it was running around 6GiB for the whole build with some
brief spikes to maybe 8GiB.  So that seems unlikely to be your problem.

You run your VM (virtual storage controller) in AHCI mode or not?  That
should be the standard option for a recent Windows VM, but if not, then
rather abysmal disk performance is semi-expected.
