At least from the statistics of BackBlaze, this is the case.
Cloud storage service provider BackBlaze released the hard drive failure data for the second quarter of 2018 - in fact, the hard drive failure data spoofed on the Internet is derived from the data provided by the service provider. The hard drive manufacturer only provides paper data, never Explain the failure rate of practical applications.
It is obviously not enough to look at a quarter. The most convincing is the life cycle data. According to the statistics table of this statistical window spanning five years, the 3TB and 6TB red disk of Western Digital will be the first place in the year. It is Seagate's famous DM series desktop 4TB model - it is still much better than the top two:
The reliability of the Western Digital Red Disk has been discussed in the major downtime forums. Complaints are often concentrated on the 4TB models of the series. However, from the above data, 3TB and 6TB seem to be more terrible. From personal experience, a 10,000 hour The 8TB red disk also has a yellow warning.
In summary, the Western Digital low-speed disk (the spindle speed is below 7200 rpm) with poor reliability is not reliable; Seagate has been stunned, especially for large-capacity disks such as ST8000NM0055 (enterprise air disk) and ST10000NM0086 (Enterprise-grade sputum plate) These two models of a best-selling Seagate model have satisfactory reliability – especially the latter, with an annual failure rate as low as 0.32%, which seems to be lower than paper data.
Be kind to the young lady, starting from the big house.
In addition, contrary to everyone's intuition, it is not the more the number of discs, the higher the efficiency.
BackBlaze specifically mentioned Toshiba's first helium disk: MG07ACA 14TB. Because the magnetic density of the disk is not high (1.56TB for a single disc), Toshiba stuffed nine discs in the filling plate to form a 9-disc 18-head complex. There are no problems with the 20-plate operation for three weeks.
BackBlaze has ordered another 1200 MG07ACA14, and large-scale application data will be released in the third quarter.
