Is there any functionality that allows reading binary file in chunks?

Currenty I am using the following query to read binary files:

SELECT image_data.BulkColumn FROM OPENROWSET(BULK ‘C:bigfile’, SINGLE_BLOB) as image_data

When size of the file is about 3 GB, the query takes about 50 seconds to execute.

When I am trying to extract a chunk from varbinary:

SELECT SUBSTRING(image_data.BulkColumn, 1, 15) FROM OPENROWSET(BULK ‘C:bigfile’, SINGLE_BLOB) as image_data

it takes about 28 seconds, no matter what the value of substring-offset is.

Are there any other ways to make the file-to-sql gateway in a more effective way? I don’t want to store large binary data in the database.
