What's the fastest way to bulk insert a lot of data in SQL Server (C# client)

Question

I am hitting some performance bottlenecks with my C# client inserting bulk data into a SQL Server 2005 database and I\'m looking for ways in which to speed up the process.

Answer 1

Yes your ideas will help.
Lean on option 1 if there are no reads happening while your loading.
Lean on option 2 if you destination table is being queried during your processing.

Question. Your inserting in chunks of 300. What is the total amount your inserting? SQL server should be able to handle 300 plain old inserts very fast.
