Large files can be kept out of the granular model database.

To do this, add a tagged value to the blob/text/image attribute: ExternalBlobStorage = true

This is a Turnkey-only functionality, and the files will be stored (with the simplest out-of-the-box solution) on disk at App_Data/BlobStorage.

They will be named: Class.Attribute.Guid.blob

Currently, they will not be automatically cleaned.
