The hard drive reliability report lists three drives that have never failed
[ad_1]
Backlight Publish Yesterday it released its drive statistics report for the second quarter of 2021. Although the failure rate has increased overall, the company found that none of the three hard drives failed. But don’t use it as a ringing (or will it spin?) endorsement. There are some important caveats regarding the reliability of these specific drives.
The problematic models are Seagate ST6000DX000, HGST HUH721212ALE600 and Western Digital WUH721816ALE6L0. Among them, only Seagate hard drives have been used for more than two years, and the company only collected statistics on 886 of them. This pales in comparison to the 177,935 drives examined in this report.
However, the performance of Seagate hard drives is still worth noting, as these drives have been used for an average of 74 months and have a lifetime failure rate of 0.92%. WD and HGST drives have been in use for 3 months and 21 months, respectively, so their 0 (WD) and 0.41% (HGST) failure rates may increase as they continue to age.
Compared with the average, these interest rates are still very low. Backblaze stated that the annual failure rate of all its drives increased from 0.81% to 1.01% year-on-year. “The growth is within our confidence interval, the company said,” but the future is worth watching. “It does not attribute the increase in drive failures to anything special.
Backblaze also updated its Comparison of HDD and SSD Boot drive failure rate. The company stated that its first attempt was “doubtful because each type of drive is at a different point in its life cycle”, so it “adopted the HDD boot drive used at the end of the fourth quarter of 2020 and returned it in time Looking at the end of the fourth quarter of 2020, their average age and cumulative driving days will be similar to the same attributes of SDD.”
This prompted the company to check the HDD boot drive information at the end of 2015. It found that “when we control the use of the same drive model, the same average drive life, and similar drive days”, the HDD failure rate will increase by 10 times, and the comparative failure rate reported in the first quarter will drop below 2 times that of the SSD.This is still a compelling reason to consider one of them The best solid state drive As your startup drive instead of using a mechanical hard drive.
