Backblaze report shows slight uptick in HDD failure rates

Cloud backup vendor Backblaze issued its latest quarterly findings for hard-disk drive (HDD) reliability, and it shows a slight uptick in failure rates — but hardly something to fret over.

All told, Backblaze has 106,238 hard drives spinning in three data center colocations, and every quarter it highlights the failure rate of each model drive it uses. The company first came to prominence several years ago when it highlighted an abnormally high failure rate of Seagate drives.

The problem arose about two years after massive floods in Thailand (around 2011) ruined the manufacturing facilities of several hard drive manufacturers, with Seagate taking it especially hard. I did some reporting back then for a now-defunct publication and found out that some corners were cut to get hard drive production going again and that those cuts resulted in a bunch of time bomb hard drives with higher than average failure rates.
