    You should use the DataReader, it is designed for buffering DataSets in memory:

    Using the DataReader can increase application performance both by retrieving data as soon as it is available, rather than waiting for
    the entire results of the query to be returned, and (by default)
    storing only one row at a time in memory, reducing system overhead.

    Assuming you are consuming the data in a application and not writing an export application, then BCP would only slow you down. BCP would be the appropriate choice if you were only concerned with doing an export.
