[XBOX360]报告称X360故障率16.4％ 三红占六成



有关Xbox 360的故障率到底多高，各家都有各家的说法：Peter Moore还在微软的时候曾宣称只有正常的3％，而一些零售商放言说已经达到了惊人的1/3。

致力于保护电子商务公平交易的SquareTrade最近发表了一份报告，根据对1000多份质保个例的统计得出结论，X360的故障率实际为16.4％，而PS3和Wii使用几百份样本进行统计的结果为3％。

报告还指出，这些出现故障的X360中有60％左右都是致命的三红问题，大部分都符合微软扩展质保计划。

SquareTrade CEO Steve Abernethy表示，随着X360使用时间的越来越长，散热缺陷暴露出来的可能性也会越来越大，故障率也将有所提高，不过他同时强调说，他们并未统计不同版本X360的故障率，但“估计绝大部分都是最初版本的”，也就是新版主机要安全得多。

根据1000多个样本进行的统计能在很大程度上保证结果的可靠性，不过这些样本都仅限于SquareTrade的服务范围，并不具备普适性，因此这个16.4％的故障率也不代表所有X360产品的情况。

Report Claims Xbox 360 Failure Rates at 16%
Significantly lower than some estimates, but higher than Microsoft's.



There's been a lot of press about Microsoft's red ring problem. Estimates of the problem have been all over the map, and when he was working for Microsoft, Peter Moore referred to them as a moving target. Company estimates pinned it at a fairly normal 3%, while some retailers have put the percentage as high as 1/3 of all systems.

A new report claims the truth is somewhere in the middle. SquareTrade deals in selling warranties for electronics, and has amassed their over 1000 warranty claims to come up with some interesting data. The findings were a 16.4% failure rate of Xbox 360 systems, versus a roughly 3% rate for the Sony PlayStation 3 or the Nintendo Wii with sample sizes in the high hundreds. The well-known "Red Ring of Death" error accounted for about 60% of those hardware failures, and thus most system-breaking problems are covered by Microsoft's extended warranty plan.

SquareTrade CEO Steve Abernethy speculated that the future may see an even higher percentage. "It is reasonable to believe these failure rates will increase over time, since the Xbox 360 failure issues tend to increase with prolonged use where overheating appears the main culprit," he said. Abernethy went on to note that while the company didn't track the different variations of the 360, he "would estimate most if not all were the original motherboard."

In taking statistics, the two most important factors are sample size and randomness. By using a pool of over 1000 redeemed warranties, the report's sample size is sufficient. On the other hand, since the sampling was taken from people who have to seek SquareTrade's warranty service out, the possibility exists that the randomness factor could be skewed, leaning towards heavy system users who are more likely to overheat their 360s. This doesn't invalidate the report by any means, but it is worth keeping mind.

1UP has contacted Microsoft for comment, but as of press time we haven't received a response.

故障率是怎么算的 没有时间概念吗
一年内三红的16％我信
两年怎么也得50％＋了吧
