I/O performance i Windows
Standard Windows 2003 I/O function calls for writing to disk are effective for small and moderate sized files, but deteriorate in performance as file sizes grow beyond 100 Gigabytes in size. Disk writes of large files writing directly to disk arrays using the Win32 API offers performance improvement of 10X over standard Windows function calls for real-time applications that require consistent performance over the entire file.
