MX100 correct settings for GC on macbook pro.

Hi all,


I read on Knowledge Base that:


"To prevent the SSD performance from degrading again in the future you can adjustment your power settings, to make sure that the SSD stays powered on when your computer goes into sleep mode.

On a Mac computer:

- Go to System Preferences
- Go to Energy Saver
- Make sure  'Put the hard disk(s) to sleep when possible' is unchecked."



...but, according to Apple:


"Put hard disks to sleep when possible


Note: Solid-state drives (SSD) do not use a motorized mechanism to read or write data. For Mac computers that only include a built-in solid-state drive, this setting does not affect the built-in drive. It only applies to externally connected, mechanical drives."



Who is right?

Is the note from Apple referred just to the Apple approved ssd?

Should I uncheck it or not to be sure that GC is running overnight?



Thank you,

Hi g,


We recommend changing the power settings as the knowledge based article states. The SSD needs time to perform Active Garbage Collection. We see a lot of customers that do not have their settings changed that run into issues with their SSD because of this. Please let us know if you have any other questions or concerns.
