SSD disks have a lower failure rate than conventional HDDs


The tables are turned, SSD disks are no longer a risk even for cloud solutions. Increase the capacities and we can finally put the prehistoric disks to rest.

Most users believe that regular spinning disks are more reliable than SSDs, which simply die out of boredom, or their cells begin to die. But as a report from Blackblaze shows, the tables are turning. This company focuses on cloud and backup and uses both SSD and HDD drives. That’s why he also keeps statistics and analyzes how each solution copes with many years of demanding traffic.

It turns out that although the failure rate is similar in the first four years and stays around one to two percent, it breaks down quite fundamentally around the fifth year of operation. At that time, HDDs have a relatively sharp increase in the failure rate, and after seven years it is already at seven percent. However, even in the fifth year, SSD drives are around one percent. The statistics are slightly distorted by the fact that the company Blackblaze has been using SSD disks for only five years, while the HDD statistics have been kept since 2014. So it will be interesting to see if the SSD will also break after a certain period of time, or if it will maintain a low bar of around one percent. A well-made SSD simply has to withstand the next ice age.
