Hi! I have played around with raid10,f2 on a 2 disk array set, and I really liked the performance on the sequential reads. It looked like double up on the speed, about 173 MB/s for two SATA-2 disks. I then went on to look at my 4 new SATS-2 disks, to have the same kind of performance I made the array by: mdadm --create /dev/md3 --chunk=256 -R -l 10 -n 4 -p f2 /dev/sd[abcd]1 And my first tests showed a sequential read rate of 320 MB/s. Impressive! I then tried it a few more times, but then I could not get more than around 160 MB/s, which is less than what I got on 2 disks. Any ideas of what is going on?
