In my PC I have 1 TB slow HDD and 120 GB fast SSD. I am curious which one of my drives should be used for Ubuntu installation.
I plan to use Windows without dual-boot - by virtualizing it with QEMU (IOMMU, VT-d). E.g. I am going to use QEMU virtual HDD files as HDD in guest Windows.
I wonder if there is any difference if the virtual HDD file will be on "clean" SSD, or it will share same drive with Ubuntu installation. Can I improve Windows guest performance by keeping host OS on another HDD than guests's HDD, or it is completely irrelevant for QEMU?
