The dataset on which this report is based is available for download on our Drive Stats Test Data webpage. In this report, we’ll show the Annualized Failure Rate (AFR) for these drive models over various periods of time, making observations and providing caveats to help interpret the data presented. There were 13 different models in use, most of which are considered consumer grade SSDs, and we’ll touch on why we use consumer grade SSDs a little later. OverviewĪs of December 31, 2022, there were 2,906 SSDs being used as boot drives in our storage servers. In addition, we take our first look at the temperature of our SSDs for 2022, and we compare SSD and HDD temperatures to see if SSDs really do run cooler. In this report, we look at the failure rates of the SSDs that we use in our storage servers for 2022, for the last 3 years, and for the lifetime of the SSDs. The workload is similar across all the SSDs included in this report. Each day they also read, write, and delete log files and temporary files produced by the storage server itself. Boot drives in our environment do much more than boot the storage servers. Since that time, all new storage servers and any with failed HDD boot drives have had SSDs installed. We started using SSDs as boot drives beginning in Q4 of 2018. This is opposed to our traditional Drive Stats reports which focus on our hard disk drives (HDDs) used to store customer data.
The SSD Edition focuses on the solid state drives (SSDs) we use as boot drives for the data storage servers in our cloud storage platform. Welcome to the 2022 SSD Edition of the Backblaze Drive Stats series.
