@gravyface, here's the output from Bonnie on an ESXi VM. The Hyper-V VM... well, it's still running the benchmark.

@gravyface: I'm running sudo dd if=/dev/zero of=/root/testfile bs=4M count=1000. I'll try bonnie.

@Nils, I followed these steps before posting my question. I will update the OP to note this fact.

@Bigbio2002, that was quick: impossible to install ubuntu on hyper-V SCSI: "no disk drive was detected"

@Bigbio2002, the switch to SCSI is going to require a rebuild, so I'll report back tomorrow.

@Bigbio2002, the default: IDE. I'll switch it and see if it makes a difference.

I have not tried CentOS. I've only tried Ubuntu and Windows 7. I do need to run Ubuntu ultimately because it's part of a continuous integration process that needs to pass its unit tests and build ubuntu binaries for shipping. If installing a CentOS VM would help for diagnostic purposes I can do that, but I can't imagine how it would. My current best option is to convert the server to an ESXi host.

Did that. Edited /etc/initramfs-tools/modules, did update-initramfs -u, rebooted, and confirmed modules were running with the command lsmod | grep hv_. Good suggestion though, that could be the cause for others with the same problem, thank you.
