第三季的数据首次加入了 10TB 跟 12TB 的资讯。
不过因为是新添购的硬盘，目前返修率都还是0，还需要观察长一点的时间。
节录其中一段，尤其最后一句的总结...
本季度的硬盘故障率为1.84％，是我们历史上最低的季度。
有几个因素有助于此，但突出的一个因素是使用硬盘的平均年龄。
只有 4TB HGST（HDS5C4040ALE630）的平均年龄超过4年 - 精确到51.3个月。
所有其他硬盘的平均年龄小于4年，其中近80％的硬盘都不到3年寿命。
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.
