Hello,

if you order a MBP with the original Apple SSD: is the sudden motion sensor enabled?

:)
 
Yes, its enabled by default with an Apple SSD.

Find the current status of Sudden Motion Sensor:

  1. From the Finder's Go menu, choose Utilities.
  2. In the Utilities folder, open Terminal.
  3. When the command line appears, type sudo pmset -g and press Return.
  4. Type in the administrator password when prompted and hit Return. This command queries the computer for the current setting of the Sudden Motion Sensor, which you can determine by locating the ams entry (in Mac OS X 10.3) or the sms entry (in Mac OS X 10.4, 10.5, 10.6, and 10.7) and looking to the right to determine its value. The default setting is "1" (turned on).

Disabling the Sudden Motion Sensor in Mac OS X 10.4, 10.5, 10.6, and 10.7:

  1. In Terminal, which should still be open from the previous step, you can disable the Sudden Motion Sensor by typing sudo pmset -a sms 0 and pressing Return (changing the setting to a zero disables the module).
  2. Type your administrator password when you are prompted and press Return.
  3. Type the sudo pmset -g command again to be sure that the setting has been applied.

So is it recommended to keep the SMS on for any kind of SSDs in Macbook Pros? Or is it better to disable it?
 
Okay. And as far as SMS is concerned - is it 100% proven that it only works for the main HDD bay and not the Optibay as well?
 
Yes, its enabled by default with an Apple SSD.

sudo is not required for the "pmset -g" command. Users have access to this information too.

I don't know about the others, but my 13" 2011 MBP has SMS for my OptiBay HDD and it works 100% tested.
