Which is better DataReader or DataAdapter?
DataAdapter is used to execute SQL statements and is used to populate the results of SQL Query into a DataSet or DataTable. DataAdapter gets all the rows of the executed SQL statement at once and populates into DataSet or DataTable in memory and hence DataAdapter is bit slower compared to DataReader.

If you’re doing purely data operations (as your question suggests), you could rewrite your code which is using the data to be T-SQL and run natively on SQL.
This has the potential to be much faster, as you will be working with the data directly and not shifting it about.
