Backblaze is an American recognized company that deals with data storage for home and business users as well as data storage in the cloud. Since it uses thousands of hard drives to store customer data, it can definitely give us insight into the most reliable hard drives today. Of course, hard disks of different capacities and different models were used, and last year’s HDD reliability measurements were also made.
Backblaze analysis showed that Seagate hard drives are currently the least reliable. Especially their model ST14000NM0138 with a capacity of 14 TB. Of the total 1,616 units, 77 or 4.79 percent quit. Interestingly, Seagate also produced the most reliable hard drive, the ST6000DX000.
The Seagate ST6000DX000 hard drive with a capacity of just a few gigabytes has proven to be by far the most reliable. Last year, only 0.11 percent of them were canceled. The WD 16TB HDD (WUH721816ALE6L0) also performed well. It had a perishability rate of just 0.14 percent. Toshiba’s same-capacity engine (MG08ACA16TE) already has a wear rate of 0.91 percent. The average life of the hard drives was 3.57 months, which is not a lot.
It is noteworthy that at the end of 2021, Backblaze had as many as 202,759 hard drives in operational use. Of these, a total of 1,820 hard drives failed. This means, on average, that a good percentage of all hard drives crashed last year.
