    I have a table that's 10GB. There is a ntext column that holds the largest portion of the data. When I check the estimated compression for this table it only shows a 10MB reduction. That seems strange to me. Why would it not be able to compress that?

    The only thing I see in BOL that might be a hint is the following:

    "Because of their size, large-value data types are sometimes stored separately from the normal row data on special purpose pages. Data compression is not available for the data that is stored separately."
