storage requirement of vCenter 7.0

just checked the installation guide https://docs.vmware.com/en/VMware-vSphere/7.0/vsphere-vcenter-server-70-installation-guide.pdf

https://docs.vmware.com/en/VMware-vSphere/7.0/vsphere-vcenter-server-70-installation-guide.pdf

i discovered that the tiny environment requires 415GB default storage size and my question is:

if i use a storage which size is smaller than 415GB (e.g. a 300GB HDD) to load the VCSA, will the deployment of tiny vCenter server 7.0 fail for sure?

or this deployment will be working just fine but the database cannot expand in the future?

thanks in advance~!
