Will it be the same? For example, 300GB virtual machine disk space = 300GB physical disk space.

I am trying to decide if I should go for 2TB or 4TB SSD. I want 1TB for Mac OS and 1TB for Windows bootcamp. So a 2TB SSD is sufficient. However, if I want to have a virtual linux machine with, say 200-500GB, how much additional physical storage do I need to add? Is virtual machine storage to real physical storage relationship one to one?

Virtualisation will generally by default use "thin provisioning" with disks.

This means that if you create a 300gb virtual drive, Windows will see 300gb but it will only take up as much physical space as is required by Windows and any installed files.

As the Windows VM grows, the physical space used by the virtual disk will expand up to a maximum of the allotted 300gb.

Thanks. So if I need 1TB for MacOS and 300GB for linux vm, I end up needing 1.3TB for MacOS?
