You won't be able to speed up the process of reading to disk. If you're calculating at the same time as you're writing, parallelizing will help. But the pure writing will be limited by the bandwidth of the lane between processor and hard drive and, more notably, by the harddrive itself (my hard drive does 30 MB/s, I've heard about raid setups serving 120 MB/s over network, but don't rely on that).
