Should TRIM be enabled on a Samsung 840 EVO?

AFAIK OS X (as well as Windows 7 and up) automatically enable TRIM if a SSD is used. You can check whenever your SSD is recognised as SSD (Solid State) or as HDD (Rotational) in System Profiler/System Information Serial-ATA section > Medium Type. The same section has TRIM Support information (Yes/No).

Chameleon bootloader does not provide any means to turn TRIM on or off and Mac OS X does not enable TRIM by default on all SSD (it certainly is not on my Samsung PM830 SSD).

 

Check if TRIM Support is available and set to Yes or No in System Report->SATA. If it's available but set to No, use a tool such as Chameleon SSD optimizer to turn it on. Remember that you would probably have to re-enable TRIM after every update.

I did link to the optimizer, not the bootloader :P

I'm just wondering if it's recommended to be turned on for my SSD model?
