RBS Third Party Provider with Sharepoint

Our SharePoint content database size is increasing day by day...we are assuming it will reach upto 1 TB. currenty the size is 136 GB. We are launching the application in different location. My company plans to use RBS for this.

In technet website, for using RBS(remote Blob Storage) with Sharepoint 2010 below is the recomendataion:-

For using Remote BLOB Storage (RBS), the total volume of remote BLOB storage and metadata in the content database must not exceed the 200GB limit.<//span>

I want to know that the 200 GB limitation is only fo FileStream RBS which microft provide with SQL server or this limitation is valid for third party providers (like Metalogix,AvePoint and others).
