Do I need to spin down my SATA HDD to save power?
I have a new HTPC that is on 24/7 running MythTV, but only used for a few hours when recording or playing back. It has a relatively modern HDD in it:

I think.
I was reading:

and it suggests spinning down HDDs. It also says that, because the HDD is SATA, this is not easy to do. I then came across this:

which says:
"It's was decided user-configurable powermanagement was not really required when modern hard disks have really intelligent powermanagment."

Here's my question - assuming a standard Mythbuntu install with no changes to hdparm etc., will my HDD move into those "Standby" or "Sleep" modes automatically, without any intervention from the OS, and reduce the power consumption to less than 1W? If not, is there some AHCI command or something that I should be using to make them do so?
Given that it is running constantly, I am also a little concerned about wear and tear on the disk. Are these (I hope) automatic/low-power states also low wear and tear, or should I be trying to manually power it down for this reason?
Thanks in advance for any help!
