Regarding the “” setting …

On the following Apple Support webpage, set to macOS Sonoma:

Under the heading, “Specify sleep and wake settings for a Mac laptop”

It includes the option:

Put hard disks to sleep: Turn on “Put hard disks to sleep when possible.”

So the option should be available on laptops. ?But that option specifically mentions hard disks — not SSDs. ?

My internal drive is an SSD and, as I mentioned yesterday, I didn’t have any external disks connected to my 2019 MacBook Pro yesterday when I captured that screenshot that showed that option missing from my available Settings Battery Options. ?This morning I connected a HDD to my Mac and Settings Battery Options now shows the option to put hard disks to sleep. ?See the attached screenshot. ?The option doesn’t show up when I have only have an external SSD attached.

I have the impression that that option, which specifically mentions hard disks, only applies to HDDs, not SSDs. ? However, I have no idea as how to prove it, other than the fact that it’s missing when no HDDs are connected. ?I’ve sent a message to Crucial support asking about their article. ?I’ll post an update after I get a response back from them.
