By far the worst PC component I have come across containing LEDs is Kingston's HyperX Fury RGB SSD [1]. It's a 2.5" SSD with 75 LEDs! These LEDs generate so much heat (70°C+) that the drive thermal throttles and either prevents the operating system from booting or causes significant performance issues [2].

- userbinator 7y agoLife expectancy 1 million hours MTBF Garish LEDs aside, marketing that sort of blatantly false exaggerated spec should be illegal. 1M hours is over 100 years.
- TylerE 7y agoMay well not be unreasonable for a solid state component. Also, keep in mind that MTBF is not expected lifetime or anything at all like that. What a 1 million hour MTBF actually means is that if you had 1 million of these drives running at the same time, you'd expect one failure per hour. (Or similarly, if you had 1000 drives, you'd expect a failure every 1000 hours).
- markwkw 7y agoFollowing your logic: 100 drives - failure every 10,000 hours 10 drives - failure every 100,000 hours 1 drive - failure every 1,000,000 hours... How is this not expected lifetime? [edit: split lines]
- barrkel 7y agoThe mean rate of failures over time may not be constant, but it may have a mode for an expected life time window. This modal mean rate of failure is what's being described, I reckon. It would be nice to know the time window, but I'd expect it to be somewhere in the 5 to 10 year range.
- wumms 7y agoFor a 5-year life span 1M hours MTBF (114 years) mean the probability of an error for a single drive is about 4.3% (1-e^-(5/114)). That equals 0.86% Annual Failure Rate (AFR). Backblaze regularly provides their real-world-usage drive stats: https://www.backblaze.com/blog/backblaze-hard-drive-stats-q1-2019/ https://www.backblaze.com/blog/backblaze-hard-drive-stats-q1... Seagate announced they would use AFR instead of MTBF in the future: https://www.seagate.com/de/de/support/kb/hard-disk-drive-reliability-and-mtbf-afr-174791en/ https://www.seagate.com/de/de/support/kb/hard-disk-drive-rel...
- TylerE 7y agoThose rates are surprisingly low considering that's spinning iron. I'd love to see a similar data set for SSDs. Of course, it also depends on what you count as a failure. Is a drive that can no longer write but can still read a "failure"? Probably - but that's a considerably softer way to fail than a hard drive with a bad bearing or head.
- imtringued 7y agoA lot of SSDs that fail early, fail because of their firmware. That MTBF probably only covers the reliability of the flash chips but not the controller.
- Dylan16807 7y ago> 0.86% So my comment is 100% nitpick but I do want to make a point here. X year failure rate divided by X is not the same as AFR. AFR will always be higher, because it has to compensate for each year's pool of potential failures shrinking. The correct equation is already there, 1-e^-(n/114), and the correct number is .87%. And while that's only a percent off, it's lucky to only be a percent off. If MTBF was 113 years it would be .86 vs. .88, which is the difference between two digits of accuracy and one and a half digits of accuracy. Losing a quarter of your accuracy is not great!
