Adding SSD to MBP (2012). TRIM? I'm planning to add a Samsung 830 (256GB) SSD to a MacBook Pro 13" (Mid-2012 model). It'll be installed into the default HDD area and the existing HDD will be moved into the optical drive bay.

Obviously Apple only enable TRIM on SSDs installed by themselves. Is there an official way to enable TRIM on an SSD the 'Apple way', or will TRIM Enabler be required? Can anyone offer some reassurance on using this software? I'm very wary of using it given that it's essentially a kernel hack.
There is no official way to enable TRIM on non-Apple drives. In all likelihood, idle time garbage collection on a Samsung 830 will be sufficient to maintain performance so you might want to ignore TRIM unless you see a problem.

I've been using that drive in a late-2007 MacBook for months even when the drive is full and have not seen any issues without TRIM. Not an exact comparison as the lower speed interface on mine might mask any problems but still a positive sign.
