-D1 is Cloudflare’s native serverless database. D1 allows you to build applications that handle large amounts of users at no extra cost. With D1, you can restore your database to any minute within the last 30 days.
+D1 is Cloudflare's managed, serverless database with SQLite's SQL semantics, built-in disaster recovery, and Worker and HTTP API access.
+
+D1 is designed for horizontal scale out across multiple, smaller (10 GB) databases, such as per-user, per-tenant or per-entity databases. D1 allows you to build applications with thousands of databases at no extra cost for isolating with multiple databases. D1 pricing is based only on query and storage costs.
 
 Create your first D1 database by [following the Get started guide](/d1/get-started/), learn how to [import data into a database](/d1/build-with-d1/import-export-data/), and how to [interact with your database](/d1/build-with-d1/d1-client-api/) directly from [Workers](/workers/) or [Pages](/pages/functions/bindings/#d1-databases).

+### How much work can a D1 database do?
+
+D1 is designed for horizontal scale out across multiple, smaller (10 GB) databases, such as per-user, per-tenant or per-entity databases. D1 allows you to build applications with thousands of databases at no extra cost for isolating with multiple databases, as the pricing is based only on query and storage costs.
+
+- Each D1 database can store up to 10 GB of data, and you can create up to thousands of separate D1 databases. This allows you to split a single monolithic database into multiple, smaller databases, thereby isolating application data by user, customer, or tenant.
+- SQL queries over a smaller working data set can be more efficient and performant while improving data isolation.
+
+:::caution
+Note that the 10 GB limit of a D1 database cannot be further increased.
