    这几天周围最可靠的硬盘是哪一个? 当谈到避免灾难性的磁盘故障时,顶级品牌出来的还有HGST根据一些新的研究。

    这是来自Backblaze的年度HDD统计数据,现在在判断硬盘驱动器的相对坚固性方面是非常有名的,数据来自云存储公司在生产使用中的大量的71,939旋转磁盘。

    HGST占了这些驱动器的24,545,而在2016年期间经历的仅仅132个故障,令人艳羡的失败率为0.6%。

    东芝第二次出现故障率为1.27%,但是这只是一个非常小的样本,只有237个驱动器,所以在这方面必须采取一点盐。

    希捷可能已经排在第三位,失败率为2.65%,但那是超过了一个巨大的45,531盘。 西部数据带来的后端故障率为3.88%的1,626硬盘驱动器;再次,较小的样本,但略高的驱动器死亡的高百分比。

    规模确实重要……

    按照硬盘的大小而不是品牌,总的趋势是驱动器越大,失败的可能性越小。 8TB驱动器的故障率为1.6%,6TB型号为1.76%,瑞星为4TB硬盘的2.06%。

    规则的一个例外是3TB驱动器实际上最不可能失败,在2016年期间的死亡率只有1.4%。

    理所当然的是,在1.4%和2.06%之间并没有巨大的差异,但它仍然值得铭记,3TB硬盘似乎是整体上最可靠的,其次是8TB型号。

    在Backblaze去年的报告中,HGST也处于极点位置,尽管其整体失败率为1%,今年已大幅提升,下降到0.6%。 很明显,如果可靠性是一个首要关注 – 让我们面对它,与硬盘驱动器它总是是 – HGST制作一些顶尖的磁盘。

    Which is the most reliable hard drive around these days? When it comes to avoiding catastrophic disk failures, the top brand out there is HGST according to some new research.

    This comes from Backblaze’s annual HDD statistics, which are by now quite famous in terms of judging the relative sturdiness of hard drives, with the figures being derived from the cloud storage firm’s considerable collection of 71,939 spinning disks in production usage.

    HGST accounted for 24,545 of those drives and experienced just 132 failures across the course of 2016, an enviable failure rate of 0.6%.

    Toshiba came second with a failure rate of 1.27%, but this was over a very small sample of just 237 drives, so has to be taken with a pinch of salt in that respect.

    Seagate might have been in third place with a failure rate of 2.65%, but that was over a colossal 45,531 disks. Western Digital brought up the rear with a failure rate of 3.88% across 1,626 hard drives; again, a smaller sample, but a slightly concerning high percentage of drive deaths.

    Size does matter…

    Going by size of the hard disk rather than brand, the general trend is that the bigger the drive, the less likely it is to fail. 8TB drives had a failure rate of 1.6%, with 6TB models on 1.76%, rising to 2.06% for 4TB hard disks.

    The one exception to the rule is that 3TB drives are actually the least likely to fail with a death rate of just 1.4% over the course of 2016.

    Granted, there isn’t a massive difference between 1.4% and 2.06%, but it’s still worth bearing in mind that 3TB drives seem to be the most reliable overall, followed closely by 8TB models.

    In Backblaze’s report for last year, HGST was also in pole position, albeit with an overall failure rate of 1% which has been improved considerably this year, dropping to 0.6%. It’s clear that if reliability is a prime concern – and let’s face it, with hard drives it always is – HGST makes some top-notch disks.
