 ### Scaling to throughput units
 
 Event Hubs traffic is controlled by [throughput units](event-hubs-scalability.md#throughput-units). A single throughput unit allows 1 MB per second or 1000 events per second of ingress and twice that amount of egress. Standard Event Hubs can be configured with 1-20 throughput units, and you can purchase more with a quota increase [support request][support request]. Usage beyond your purchased throughput units is throttled. Event Hubs Capture copies data directly from the internal Event Hubs storage, bypassing throughput unit egress quotas and saving your egress for other processing readers, such as Stream Analytics or Spark.

 Event Hubs Capture is metered similarly to throughput units: as an hourly charge. The charge is directly proportional to the number of throughput units purchased for the namespace. As throughput units are increased and decreased, Event Hubs Capture meters increase and decrease to provide matching performance. The meters occur in tandem. For pricing details, see [Event Hubs pricing](https://azure.microsoft.com/pricing/details/event-hubs/). 
 
+Note that Capture does not consume egress quota as it is billed separately.

 ## Integration with Event Grid 
 
 You can create an Azure Event Grid subscription with an Event Hubs namespace as its source. The following tutorial shows you how to create an Event Grid subscription with an event hub as a source and an Azure Functions app as a sink: [Process and migrate captured Event Hubs data to a SQL Data Warehouse using Event Grid and Azure Functions](store-captured-data-data-warehouse.md).
