Some hard disks are more reliable than others, and a new report has cast further light on which drives are less likely to fail.
Backblaze produces regular reports on hard disk reliability and the latest one for Q1 2016 was conducted using over 61,000 HDDs in data centers, with no less than a billion hours of operation in total between them.
The good news is that in the big picture, across all hard drives surveyed, failures decreased, and in fact the recorded annual failure rate of 1.84% is the lowest quarterly number that Backblaze has ever seen. In other words, hard disks are getting more reliable generally speaking.
As to which is the most reliable brand, once again the lowest failure rate was achieved by HGST with 1.03% across 22,731 HDDs (i.e. one in a hundred drives failed in the year running up to Q1 2016).
The next best overall average was Toshiba on 3.06%, although this was based on a very small amount of drives, just 238 of them. Seagate had a failure rate of 3.48%, but that was over a far greater sample of 36,863 drives.
Western Digital brought up the rear with a failure rate of 6.55%. Again, that was …read more
