I am checking raid5 performance. I am using asynchronous ios with buffer size as the stripe size. In this case i am using a stripe size of 1M with 2+1 disks. Unlike raid0 , raid5 drops the performance by 50% . Why ? Is it because it does parity checkings ? thank you -- Raz - 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
