At least in suspend-to-ram (S3), power down part is not even called. [Its suspend, we are not powering off, after all.] On S3 resume you should wait for disks to spin up, so you need resume handler.
I used same stuff for S3 and S4, which means I do need to spin them down even for S4. I believe same handlers for S3 and S4 suspend/resume is right thing to do...
