That is insane. And also one of the reasons I try to avoid being a system integrator whenever possible. It just takes up too much time - so much simpler having my friendly Supermicro distributor build my server for me!
This particular build was setup to be primarily a Hyper-V host, for the VM drive I chose an Intel 750 PCIe SSD. The drive is amazing, super fast, makes traditional SSDs look like spinning disk. Choose the EVO to save a few bucks for the customer, as the server OS wasn't going to doing any heavy lifting. I never imagined that a hard drive could be incompatible with an OS.
