I have a 15 inch mid 2012 macbook pro and a 3rd party Intel SSD (INTEL SSDSC2CT240A) that reports:
TRIM Support: No. I have scoured the internet all returning varying statements from:
- Trim support is not necessary on new drives as they have their own garbage collection built into the firmware
- You should enable trim immediately or else the drive will suffer in both longevity and performance
I have stumbled across a command (that apparently made its way into the new versions of Mac OS X) called trimforce which allows for enabling of trim on 3rd party ssds. However there is a quite discouraging message warning against it

What makes it so hard for OSX to enable trim on 3rd party SSDs without having such a dangerous possibility of corruption when Windows has been doing this for a while now? Will not enabling TRIM actually reduce my SSD lifespan significantly?
