I didn't address this earlier as I assumed you, and anyone else reading this thread, would do a little background reading and realize no SATA PMP would behave in this manner.

All of them achieve pretty close to wire speed throughput. -- Stan -- To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
