> Surely it doesn’t matter when you have 10,000s of drives? Aren’t you already at a large enough sample size? If it isn’t, what is the point of them publishing this every year? I don’t know the math of the matter though. I think drive age matters? I'm not clear if they cycle drives out at a certain age or just run them until they fail. Also, if a drive is low enough in cost, then the additional cost of replacing an incremental 1% may be lower than the cost of acquisition of a more reliable drive.
