2022 M2 MacBook Pro 256gb SSD - Does "Put hard disks to sleep when possible" have any effect?

Does the setting “Put hard disks to sleep in MacOS Sonoma have any effect on a MacBook Pro with an internal SSD? I currently have it set off but was wondering if it makes any difference regardless

You can turn it ON with no problem.

I think it would only matter if you have external hard disks connected. I don’t think SSDs go to sleep like HDs do

I can turn it on but 1. Should I? 2. Does it make any difference on an m2 MacBook Pro with ssd?

No discernible difference without a mechanical reponse on an SSD.
The setting is intended for a mechanical device.

Sleep mode is not bad for SSDs. The data is stored in RAM rather than on the SSD when you put the computer into sleep mode. Therefore, when you wake up your computer, it will continue from where it left off very quickly. Excessive write cycles are the only thing that affects SSDs.

If thats the case then should i enable "Put hard disks to sleep when possible" on my M2 Macbook Pro with 256gb SDD running MacOS Sonoma? i keep getting conflating responses where some say that setting doesn't make any difference on a mac with an SSD. Now, i do have some external WD harddrives (Mechanical) that i connect to the mac sometimes when i want to move some files over to back up etc but i connect them for a very brief amount of time.

Does it affect externally connected mechanical Hard drives via USB?

I already answered to you. If you want to put the SSD in sleep mode the main advantages are:
- Faster resume
- It’s much more energy-efficient
- It’s more reliable
- Can prevent overheating

However, I recommend to disconnect external hard drives when you put your Mac in sleep mode.

Turn off “Prevent automatic sleeping on power adapter when display is off”.

Turn off “Prevent automatic sleeping on power adapter when display is off”.

Thank you. i have that turned off. i thought there was another setting that was explicitly named "Put hard disks to sleep when possible" but if there isn't then i guess i'm all set. thanks again for the help

Select also Low Power Mode -> Only on Battery.

I actually selected that to Never as i never use the macbook on a battery, its always connected to power on my desk.

Not good idea. Despite macOS optimize battery usage, is always good idea to let battery discharge to at least 20% once in a while.
