That looks down right piss poor. I was really hoping that this fix would be a permanent fix and that we'd have nothing to worry about but... I guess that's not the case.
Basically, this is a hardware issue and that the 840 EVO is flawed at the hardware level and no amount of firmware fixes will fix this issue. This is clearly a hardware flaw. Samsung tried, I give them that, now they have to step up and admit that the 840 EVO is indeed flawed at the hardware level and they need to do something about it. They have the 850 EVO now, I expect nothing short of a full recall of the 840 EVO and have them replaced free of charge with the 850 EVO.
We basically need to get the major technology news sites (AnandTech, Tom's Hardware, etc.) to cover this issue again and make it known that the issue isn't fixed and that we demand nothing short of a massive recall of the flawed hardware.
There really is no other SSD that I would even think about buying. All of the other SSDs on the market are powered by Sandforce controllers and we all know that Sandforce controllers are such buggy pieces of crap that they make Windows looks perfect in comparison.
