I have an OCZ vertex 3 120 gb in my 15".
Have enabled trim using the "apple SSD" string removal.
It works just fine, no beach balling or hangs or slow downs.
Would you recommend buying OCZ Agility 3 - it is much cheaper than this. I heard they just use a different Flash cell for this. They price the OCZ Vertex costlier because they have to pay more for Samsung.
