I love these so I'm really sad to say this: What's missing is an AFR based on deployed time in increments, not total time.
For example: there should be a sliding window (or a histogram) relating to AFR after deployment for a time frame.
IE: AFR between 0-300 days, AFR between 301-600 days, AFR between 601-900 days (etc).
Otherwise we're looking at failures historically for the entire period, which might hide a spat of failures that consistently occur 3 years in, giving a relatively unfair advantage in numbers to newer drives.
That said, I really do love these and I hope they continue.

Due to factory testing, 'the bathtub now has no left side, which makes it hard to take a bath'. https://i.gzn.jp/img/2021/12/21/black-blaze-how-long-disk-drives-last/drive-failure-by-quarter.png https://i.gzn.jp/img/2021/12/21/black-blaze-how-long-disk-dr...
