From the PlanetXbox360 feature study:

"Over the past couple months PlanetXbox360.com has been conducting a massive comprehensive study (online, via the phone, and in person), in an attempt to find out once and for all how many of the Microsoft loyalists have experienced the dreaded red ring of death. A recent study was posted on the internet that found 50% of all Xbox 360's had the RRoD issue, the findings of this study did not fall in line with those results. If you're not familiar with this phenomenon that has plagued the Xbox 360 since it's successful release in 2005 the RRoD happens because of a console hardware failure (from a number of different possibilities).

Only 10% of the entire survey stated that they did not return to the Xbox 360 after getting a ring of death, showing that even with the failure Xbox 360 fans stick by their favorite console, through the good and the ugly. The number we found of total Xbox 360 units that got hit with the RRoD will probably shock you, and hopefully clear this up once and for all."

Well only the real hardcore annoying fanboys believed the 50% BS. The 30% number is probably closer to the real number, if anything its probably still is a little lower than that.

Yeah, I think most accepted that the 50% was exagerated. It was based on an online poll so you're bound to have a few fanboys skewing the results. This sounds a bit more accurate to what was reported before the 50% thing.

Not defeding MS on this at all however, 30% is a ridiculously high failure rate for any electronic device.

Well the study says it's more like 33%, which still is rediculously high!

Let's hope that Microsoft at least does not repeat the same thing with the next Xbox

How many people were involved in this study?

I think the previous study that resulted in the 360 RROD with like 54% were conducted with around 10,000 360 owners.

I think these studies is just hard to be accurate because the people can be a group full of lucky or unlucky 360 owners. Best is to like conduct all 360 owners from like a state or even all of NA (i know thats hard)... then at least its more accurate to say this state or NA has a "X"% of RROD then just random people.

because it was 50% ?

In my memory it was something like 33,33%

Phew, only 33 % .........

I never believed it was half, 30% seems about right

I believe it could be 30% in suveys among hardcore gamers, but those numbers are always overexaggerated because the people with hardware problems are more inclined to reply in these surveys. Remember that people are lying too, to make the X360 look bad. They can claim they own a X360 who RROD, but no one can check.  True number could be less than 25% among hardcore gamers.

And if all gamers are included - casuals too - RROD rate is below 20% I would think.
