Any reason you want to use SqlBlobProvider? I'm not exactly familiar with it but I think it is quite an anti pattern to use SQL to store blob. You can, yes, but that does not mean you should 

No, the only reason is that all media is stored in the databas today. Your suggestion is to move it all to disk I guess?

But you should be able to use the plugin with SqlBlobProvider?

As I said I'm not familiar with it so I might be very wrong, but based on some very quick look on SqlBlobProvider/src/EPiCode.SqlBlobProvider at master · BVNetwork/SqlBlobProvider (github.com) it seems to use DDS to store the blob information (which is not as I original thought to use Sql Blob to store files, it still uses disk to store files). I would advise against that as DDS is quite terrible when you have big enough data in there ( a few hundreds and more)

Ok, thanks for the advise. I guess completly move media from the database is the best option, do you agree?

The assets are handled as content, and for that (the metadata) it is stored in database. I think that is fine (with a usual caveat that you don't want to put a lot (hundred of thousands) of assets in same folder, as that would overwhelm the GetChildren etc.). Other than that I think the files (blobs) should be stored in disks, not database.
