Backblaze 的 2024Q2 硬碟報告有些新的花樣：「Backblaze Drive Stats for Q2 2024」。
先大概掃一下文字的部分，可以看到 HGST 這邊的 HUH721212ALN604 有狀況，用季計算的 AFR 偏高 (但還沒高到觸發到整個生命週期的 AFR 值)：
An HGST surprise: Over the years, the HGST drive models we have used performed very well. So, when the 12TB HGST (model: HUH721212ALN604) drive showed up with a 7.17% AFR for Q2, it’s news. Such uncharacteristic quarterly failure rates for this model actually go back about a year, although the 7.17% AFR is the largest quarterly value to date. As a result, the lifetime AFR has risen from 0.99% to 1.57% over the last year. While the lifetime AFR is not alarming, we are paying attention to this trend.
比較有趣的是多了幾張圖，用四象限分類可以更清晰的看出不同型號的情況：
另外還有依照時間變化的樣子：
這樣看起來更直覺了，比起之前對表格對半天方便不少，不過少了信賴區間的資訊，要注意硬碟的量...
