# Data Storage for Data Portals
Data Portals often need to store data 😉 As such, they require a system for doing this. The systems for storing data can be classified into two types:
- Blob Storage (aka Bulk or Raw): for storing data as “blobs”, a raw stream of bytes like files on a filesystem. Think local filesystem or cloud storage like S3, GCS, etc. See Blob Storage for more on this.
- Structured Storage: for storing data in a structured way e.g. tabular data in a relational database or “documents” in a document database.
In CKAN 2 Blob Storage (and associated functionality) was known as FileStore and Structured Storage was known as DataStore.
