Working for a laptop brand for years i can give you some input on this.
EVERY brand we sold, NONE ever compared to the low RMA of the SAMSUNG SSDs, its crazy actually, we sell millions of those in last 4 years, only got like 2 to 3 RMAS. It's just stupid and insane, nothing else can compare, we tried intel, ocz, toshiba, plextor, crucial, corsair, kingston, and usually it only takes a week or two to notice the difference in reliability.
My advice is Samsung 840 Pro or the new 850 PRO, but i cant vouch with real RMA data on the last one, but according to Samsung they are even more reliable... even the warranty is longer.
