Simple persistence question

Elastic Stack Elasticsearch
1

Hi

I feel this should be a newbie question, but so far my google skills has
eluded me.

Assume I have a simple setup with two nodes, standard 5 shards and 1
replica setup, and standard local disk persistence.

When I add data to an index is it then persisted to disk only on the
primary node, or also on each replica?

In other words if each node has 250Gb of disk storage, do I have room for
250Gb documents or 500Gb documents?

Best regards
Henrik

Only for 250 Gb docs.
As each doc is replicated once.
