第三季的數據首次加入了 10TB 跟 12TB 的資訊。
不過因為是新添購的硬碟，目前返修率都還是0，還需要觀察長一點的時間。
節錄其中一段，尤其最後一句的總結...
本季度的硬碟故障率為1.84％，是我們歷史上最低的季度。
有幾個因素有助於此，但突出的一個因素是使用硬碟的平均年齡。
只有 4TB HGST（HDS5C4040ALE630）的平均年齡超過4年 - 精確到51.3個月。
所有其他硬碟的平均年齡小於4年，其中近80％的硬碟都不到3年壽命。
The hard drive failure rate for the quarter was 1.84%, our lowest quarterly
rate ever. There are several factors that contribute to this, but one that
stands out is the average age of the hard drives in use. Only the 4TB HGST
drives (model: HDS5C4040ALE630) have an average age over 4 years — 51.3
months to be precise. The average age of all the other drive models is less
than 4 years, with nearly 80% of all of the drives being less than 3 years
old.
