A recent analysis of over 5,000 hard disk drives (HDDs) indicates that a significant portion, approximately 1.5%, fail, with nearly half of these failures occurring within the first year of operation. A notable 30% of these failures happen without any prior warning. While HDDs remain a cost-effective solution for high-capacity storage, especially compared to the rising prices of SSDs driven by AI data center demand, their mechanical unpredictability and shorter average lifespan (around 807 days for failed drives) necessitate robust data backup and replacement strategies. AI
IMPACT The rising demand for SSDs due to AI data centers is increasing their cost, making HDDs a more attractive, albeit less reliable, option for bulk storage.
