Hi! I have a machine with 2 SATA disks on 2 separate buses. hdparm -t /dev/hda reports 50MB/s hdparm -t /dev/hdb reports 50MB/s I created a raid1 array with hda3 and hdc3, same partition sizes. If I do hdparm -t /dev/md0 it reports 50MB/s If I do cat /dev/md0 > /dev/null, vmstat reports 50MB/s If I start another cat /dev/md0 > /dev/null, in another console, I get 100MB/s from vmstat. Why I don't get 100MB/s on a single cat command? Some other test: cat /dev/hda3 > /dev/null& cat /dev/hdc3 > /dev/null& vmstat shows 100MB/s. Also, seems that writing is very slow (8MB/s). Any ideas?
