With disks, it is usually head seek time that is much more of a
problem than data transfer speed. And if your VMs share the same
physical disks for their virtual disk images, they are always going to
want the heads to be in different places. You may be able to avoid
some of this problem by arranging to put the virtual disks on
different physical host drives, or using raids with a very large
number of drive members. SSDs avoid it by not needing to move a
physical head to access different locations.
