Add Extra Hard Disk to macOS : A simple way to add an extra virtual hard disk to Virtual Machine running on VirtualBox and create a mount point.
Users of VirtualBox can load multiple guest OS under a single host operating-system (host OS). Each guest can be started, paused and stopped independently within its own virtual machine (VM). The user can independently configure each VM and run it under a choice of software-based virtualization or hardware assisted virtualization if the underlying host hardware supports this.
The host OS and guest OSs and applications can communicate with each other through a number of mechanisms including a common clipboard and a virtualized network facility.

On the other Hand uses of Virtual Machines
Performance. Giving your virtual machine it’s own dedicated hard disk means it isn’t competing with the host machine for access. I haven’t run tests, and the USB or FireWire bottleneck may compromises guest performance, but my inner engineer would rather have a slower guest than a slower guest and host.
Backup. A virtual hard disk is a large, frequently changing file. Most backup software, such as Time Machine, doesn’t work well with these.
Portability. To use the virtual machine on a second computer, all I need to do is copy the settings, only a few kilobytes of data. Then all I have to do is plug the external disk into whatever computer I feel like using that day.
Access. Instead of being locked away in a virtual hard disk file, my files are accessible to any computer that I can plug the drive into.
