Putting drives to sleep when you have SSDs

[Killahurts]

In My 2010 MP, I've got three Samsung EVOs and one 4TB spinner, in the four drive bays. I only use the spinner for storage and back up, so I thought it might be nice to let it spin down when not in use.. but I don't know of a way to do it individually per drive, it has to be all drives in the Energy Saver settings. I don't know what that would do to my EVOs, if anything, but I sure don't want to risk messing them up- they work so flawlessly for me now. As it has been, my settings are set with the computer and the drives running forever.

Maybe there's a utility I could get that would let me control a specific drive?
Thanks!

Not an issue. SSDs have a trickle of current when idle for Garbage Collection and the like. They can't go to sleep like a spinner.

What Apple has to say:

[b]Put hard disks to sleep when possible[/b]

This setting powers down the hard drive motor when you aren't reading or writing files from the drive. Solid-state drives (SSDs) don’t have moving parts, so this setting doesn’t affect Mac computers that use only SSDs to store data.

Consider deselecting this option if you have an internal or external non-SSD drive and you use apps—for example, pro audio or video editing software—that work better with continued read and write access to the hard disk.

Cool Mike, thanks!

I'm going to turn it on and see how everything behaves.
