This should be diminished by good disk hardware with a /write/ ram cache in the firmware. This cache is pretty small, and I'm not sure it caches writes.
Disks don't do write-caching. That is left to hardware controllers with battery-backed cache.
ISTR that sata drives have a very small write cache. For some reason I'm remembering up to 7 writes can be cached. For streamed data like BC is talking about, that is effectively nothing.
