I'm thinking of setting up a spanned disk across 3 HDDs to simplify my file storage structure. I'm trying to find how the drives spin up. Do individual drives spin up only when data stored on that disk is being accessed? Do all drives spin up when data is accessed on the spanned disk?
 
Depends on the HDD : in general only 5400 rpm drives spin down. Seagates at 5900rpm don't neither do the 7200rpm drives. what are you worried about? That the psu can't take 3 drives spinning up in the same time? Even if a drive has the heads parked will take 3-4 seconds to spin up if the data is on it and requested. If you pool them in a large single GPT partition there is no way of telling on which hdd the data will be send.
 
I wouldn't suggest using that functionality in Windows 7. You're probably better off with something like Drive Bender or Drive Pool. You'll have far better control on where files are actually stored and even the ability to have specific files/folders duplicated across all drives.

If you upgrade to Windows 10, the built in Storage Space functionality offers much of that too.

Thanks for the insight MARSTG. I'm just curious what happens for now. No worries about the PSU.

Thanks for the info on the programs JD. I'm debating whether or not I should upgrade to W10...
At this point, I'm not too worried about redundancy on the spanned volume since I back everything up nightly.

Having used both situations I would recommend Drive Bender for Win 7 and the Storage Space functionality in Win 10.

The bigger issue though is in a recovery scenario. Dynamic Disks/Volumes in Windows has never been that great...

But if you have everything backed up onto another drive outside your machine, then I guess it doesn't really matter.
