Hi! I have a machine with 2 SATA disks on 2 separate buses. hdparm /dev/hda reports 50MB/s hdparm /dev/hdb reports 50MB/s I created a raid1 array with hda3 and hdc3, same partition sizes. If I do hdparm /dev/md0 it reports 50MB/s If I do cat /dev/md0 > /dev/null, vmstat reports 50MB/s If I start two command like above, simultaneously I get 100MB/s. Why I don't get 100MB/s on a single cat command? Thank you very much! --- Catalin(ux) BOIE catab@deuroconsult.ro - To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
