Abstract
The distribution of failed HDD and SSD drives from various manufacturers by operation time in one of the world’s largest cloud storage companies Backblaze data centers for a long period has been studied. As a result of the study, time ranges with the maximum share of failed drives were determined. It was found that along with the maxima corresponding to the declared drives technical characteristics, for almost all brands there is a large number of failures also in the initial operation period. A method of taking this circumstance into account when evaluating the data centers’ effectiveness is proposed.
