Hyper-V: Benefit of Putting Virtual Hard Disks and Virtual Machines Folders on Separate Drives

  • 772

Hyper-V has two folders 'Virtual Hard Disks' and 'Virtual Machines', the first stores the virtual disks themselves and the latter stores settings, snapshots, etc.

Is there's benefit of storing these two folders on separate SSD drives to:

  1. Increase performance - reduce chances of disk related IO bottleneck

  2. Increasing individual SSD life longevity - 'Virtual Machines' folder stores .VMRS files which are equal to the amount of configured RAM on the guest OS, so this folder should get hit harder with disk writes on RAM intensive guest OSs and degrade the SSD faster.

  1. THere really is none. As you can see in the case that if you use a cluster setup, they all live in the same cluster shared volume.

    If the VM impacts performance you have a SERIOUS problem on the performance. Same with SSD longevity.
