So I have mid-2012 13" MacBook Pro and I am thinking of buying an 240-256GB SSD to replace the internal drive. I have been looking at Samsung 840 EVO but I am still undecided because it does not have a SandForce controller and I could not find anywhere whether the OS X TRIM works properly with this drive. So my questions would be: 1) Can I safely use TRIM enabler with this drive? 2) If not does it take big performance and lifespan hit ? 3) Could you maybe recommend some alternatives, preferably 200€ and under?
