+## Gain advanced storage insights
+
+Track how your Azure Blob Storage estate is evolving and uncover hidden opportunities to reduce costs, boost performance, and tighten security. Azure Storage Discovery reveals underused data, throttling risks, and ways to optimize spending.
+These insights are powered by metrics related to storage capacity (object size and object count), activity on the data estate (transactions, ingress, egress), aggregation of transaction errors and detailed configurations for data protection, cost optimization, and security.
+
+<!-- Analyze how the data estate in Azure Blob Storage is growing, identify opportunities for cost optimization, discover data that is under-utilized, pinpoint workloads that could be getting throttled and find ways to strengthen the security of your storage accounts. These insights are powered by metrics related to storage capacity (object size and object count), activity on the data estate (transactions, ingress, egress), aggregation of transaction errors and detailed configurations for data protection, cost optimization and security. -->
+
+### Interactive reports
+
+Your Discovery resource in the Azure portal offers intuitive reports that reveal trends, highlight top storage accounts, and link directly to the resources behind each chart. Quickly spot patterns, surface key accounts, and jump straight to the data—all from your Discovery dashboard in Azure.
+Filter reports by region, redundancy, performance, encryption, and more to focus on the most relevant parts of your data estate.
+
+<!-- Your Discovery resource in the Azure portal features several reports that make it simple to analyze trends over time, drill into top storage accounts, and instantly navigate to the specific resources represented in each chart. The reports can be filtered to focus on specific parts of the data estate based on Storage account configurations like Regions, Redundancy, Performance type, Encryption type, and others. -->
+
+### Organization-wide visibility
+
+Flexible scoping allows you to gather insights for multiple business groups, workloads, or groupings of resources that are meaningful to you. Analyze up to 1 million storage accounts spread across different subscriptions, resource groups, and regions within a single workspace. The ability to drill down and filter data allows you to quickly obtain actionable insights for optimizing your data estate.
+
+### Adding Storage Discovery is simple
+
+**Fully managed service** 
+The Discovery service computes and hosts your insights. No other infrastructure needs to be deployed or paid for.
+
+**No impact on storage resources**
+Your Azure Storage resources (like storage accounts) experience no transactions or performance impact when analyzing them with Azure Storage Discovery.
+
+**History provided right from the start**
+Up to 30 days of historical data is added automatically, once you deploy a Discovery workspace. All insights are retained for up to 18 months. History and retention depend on the [pricing plan](pricing.md) you choose.
+
+**Free and paid pricing plans**
+Azure Storage Discovery offers free and paid pricing plans for each workspace. The [pricing article](pricing.md) describes the differences and explains what influences the bill when choosing a paid option.

 With just a few clicks, users can answer critical questions such as:
 - How much data do I have across all my storage accounts?
 - Which regions or workloads are growing fastest?
 - Where can I reduce costs by adjusting access tiers or deleting stale data?
 - Are my storage configurations aligned with security and compliance best practices?
+!-->
 
-## How do I use Storage Discovery?
-Azure Storage Discovery can be used to gain insights across multiple dimensions. The following use cases illustrate how users frequently leverage the service:
-
-- **Unified Visibility Across the Storage Estate**<br/>
-Gain organization-wide visibility into up to 1 million storage accounts. Discovery aggregates insights across subscriptions, resource groups, and regions, enabling users to monitor their entire storage footprint in one place.
-
-- **Actionable Insights Without Engineering Overhead**<br/>
-Out-of-the-box dashboards surface trends in capacity, transactions, errors, and configuration changes. Users can drill down into specific accounts or filter by tags, regions, or redundancy settings - without writing a single line of code or deploying infrastructure.
+## From insight to action with Azure Storage Discovery
 
-- **AI-Powered Exploration with Copilot**<br/>
-Integrated with Azure Copilot, Discovery allows users to ask natural language questions like `"Which storage accounts have the highest egress this month?"` and receive visual, contextual answers powered by Kusto Query Language (KQL) behind the scenes.
+Azure Storage Discovery simplifies the process of uncovering and analyzing insights from thousands of storage accounts, transforming complexity into clarity with just a few clicks. 
 
-- **Security and Compliance Monitoring**<br/>
-Visualize and audit storage configurations to ensure alignment with best practices. Identify accounts with settings that don't align with your business needs and take corrective action.
+### 1. Use the reports
