You can store them all on the same parition on under different
directories.. But you run a risk of running out of space for all 3 at the
same time.

Man pages are your friends :D

I have not used hdparm with XFS, but like any other files system you are
just spinning the drive down to save power. I dont think there is much of
an issue with it.

Also with ext3, you will start to see slower access and read times as your
files get larger and your drive fills up. I found that with my Raid array,
and other systems using the same size of drives.
