I have a team of 3 120GB Corsair that I upgraded to 1.3.3 firmware. I still get the system hangs for about 10-30 seconds, where the operating system is "stuck." I mostly built my machine to play Battlefield 3. It is playing with the best system, but the game with Windows 7 that was fine.
The hanging seems worrying. In fact, once hung while loading a map / game Battlefield 3, and the kind of thing froze at that point until the system reached. Battlefield 3 is very new too, so it could have been the fault of the game. However, this has happened while I'm surfing the internet or doing things on the computer - not a game. I have read other reports of this unit doing this kind of behavior did not know if anyone had any idea.
