And note: Disable kv-store on your forwarders (if it is heavy forwarder) to avoid additional storage impacts.

Also It all depends on how much you are forwarding. If it is in GBs, you don't need 5GB. But just be safe and go with defaults.

Yes, it is mentioned as 5GB

https://docs.splunk.com/Documentation/Splunk/latest/Installation/Systemrequirements#Recommended_hard...

Maintain a minimum of 5GB of free hard disk space on any Splunk Enterprise instance, including forwarders, in addition to the space required for any indexes. See Estimate your storage requirements in Capacity Planning for a procedure on how to estimate the space you need. Failure to maintain this level of free space can degrade performance and cause operating system failure and data loss.
