Hi again .

I did monitor the IO of the RAID array using IOstat tool .

I'll attach the output .

One thing I noticed is that monitoring the raid array made it survive a LOT
longer than before .

I simply used dd to dump 300G of zeros into the array , while at the same time
using md5deep on the entire mountpoint .

it stopped after writing around 280G this time , I was surprised because it
never exceeded 77G before .

Tell me if you need me to do anything else .

Thank you very much .
