1. Navigate to the newly-created virtual machine, right-click on the VM, and click on Edit Settings, as demonstrated in the following screenshot:

2. Click on the drop-down menu adjacent to the New device option, select New Hard Disk, and click Add:

3. Now we see a new addition to the virtual hardware list. Collapse the drop-down menu adjacent to the newly-added hard disk to complete the configuration.

 

4. Populate the appropriate disk size within the Maximum Size:

5. Leave VM storage policy, Location, Disk Provisioning, and Sharing at default; these are typically not modified unless there are specific performance and redundancy requirements.
6. Shares and Limit - IOPs enable IOPS prioritization and disk bandwidth control, leave at the default—Normal-1000 and Limit - IOPs to Unlimited, a misconfiguration here could lead to performance issues and is best managed by the host.
7. Virtual flash read cache can be left at default. This is applicable only for certain types of read-intensive workloads and only if the hosts are equipped with flash devices to serve the purpose.
8. Leave Disk Mode at default—Dependent. This setting emulates typical physical hardware, however in VDI backed environments and certain use cases of test, dev, lab, or setup, one may choose independent disk modes.
9. The SCSI controller is automatically allocated by host based on the existing hard disks that have been provisioned.
10. Click OK to complete the process.
