I have a Mac Pro with 28 cores and 192 GB of memory and more GPU than i need. I need speed to run really large data sets in MS Access and Excel. Before setting up Parallels 17, i created a bootcamp partition and installed windows in case i was not getting the performance i need in the VM environment. When i installed P17, i decided to just run it from the bootcamp install (My Bootcamp) instead of making a new VM. Other than sacrificing drive space (I got a lot of that too), are there any other drawbacks to this type of installation - namely in performance?
