You’ll find the links to download the data files on our Drive Stats Test Data webpage. Now for the bad news: The data does not currently include a drive type, SDD or HDD, so you’ll have to do your research by model number. In fact, we have always published this data as it resides in the same files as the HDD data. Most are due to the newness of a drive, but we’ll let you know.Īs with the HDD reports, we have published the data we used to develop our SSD report.
We will explain these outliers as we go along.
For example, an AFR of 43.22% might catch your attention. As we share various tables and charts below, some of the numbers, particularly the annualized failure rate (AFR) will be very surprising to informed readers. OverviewĪs of December 31, 2021, we were using 2,200 SSDs. Each day a boot drive will read, write, and delete files depending on the activity of the storage server itself. Boot drives in our environment do much more than boot the storage servers, they also store log files and temporary files produced by the storage server. Since that time, all new storage servers and any with failed HDD boot drives have had SSDs installed. We began using SSDs in this capacity in Q4 of 2018. In our early storage servers, we used HDDs exclusively for boot drives. The SSDs in this report are all boot drives in our storage servers. We will continue to publish the HDD Drive Stats reports quarterly. Initially we expect to publish the SSD edition twice a year, although that could change depending on its value to our readers. This edition will focus exclusively on our SSDs as opposed to our quarterly and annual Drive Stats reports which, until last year, focused exclusively on HDDs. Welcome to the first SSD edition of the Backblaze Drive Stats report.
