Tejas,
You are probably running firmware AR13 or older. The drives are designed
for very power efficient archive use and they have a very aggressive
spin down timer. Once they drop to a slower speed or stopped it will
take a significant time to get back up to ready. I would highly suggest
updating to code AR14 or AR15.
The drives aren't really intended for your use model. Perhaps a cron job
that does a dd read (direct mode) of a hundred MBs or so from the md
device to dev/null every couple minutes might be enough to keep them
warm and not spun down.
