It should not take 8h to insert 200k rows on any machine made this
century. Frankly, I'm wondering if the insert is doing anything at all,
or is blocked on a lock somewhere. You say there's no concurrent
activity, but how hard did you look? Did you check that, say, the
physical disk file for the table is growing?

A different line of thought is that there's something seriously broken
about the raid configuration. Have you tried basic disk-speed
benchmarks? (Perhaps there's an equivalent of bonnie++ for windows.)
