Are SSDs as reliable as HDDs now?


Solid state drives (SSDs) have come a long way in recent years, and new data from Backblaze’s latest Drive Stats report reveals that they are now on par with hard disc drives in terms of reliability and durability (HDDs). In addition to yearly and quarterly Drive Stat reports on the performance of the drives that make up the cloud storage and cloud backup provider’s two exabytes of data storage, the company also releases Drive Stat reports on a monthly basis. Until last year, however, these reports were only concerned with the performance of the company’s hard disc drives.

Backblaze has revealed further insight into the performance of the solid-state drives (SSDs) that it employs as boot drives in its storage servers with the release of its Drive Stats report for 2021. According to Andy Klein, lead cloud storage evangelist at Backblaze, the firm began employing SSDs in this manner towards the end of 2018, albeit it also utilizes them to store log data and temporary files produced by its servers. Since introducing SSDs in its storage servers in 2018, the company has now amassed a total of 2,200 SSDs with some running in its servers for a longer period of time than others.
