The Backbone of Efficient Data Storage: Ghassan Azzi Highlights the Role of HDDs Amid Growing Data Demands
In a rapidly evolving digital landscape, Ghassan Azzi, Sales Director for Africa at Western Digital, has emphasized the importance of scalable, cost-effective data storage solutions in meeting the needs of modern businesses. As data generation continues to surge, particularly with the rise of connected devices and artificial intelligence (AI), Azzi pointed out that efficient data storage is becoming an essential consideration for datacenter managers worldwide.
Azzi acknowledged the widespread attention on flash storage due to its high performance and low latency, but warned that not all data requires such advanced storage technology. “Each application and type of data has its own access requirements, and it’s not always necessary to pay the premium for the speed of flash storage,” he explained. According to Azzi, the difference between “warm” and “hot” data is a critical factor when selecting the appropriate storage solution. For example, a globally popular music video that attracts billions of views may need to be stored on high-performance SSDs or RAM, while videos with fewer views, like those of influencers or niche hobbyists, can be effectively stored on HDDs to keep total cost of ownership (TCO) in check.
Azzi stressed that data centers must consider multiple factors beyond performance, including capacity, power, cooling, and storage density. These factors influence the overall TCO and help leaders choose the most cost-effective storage options. “Datacenter leaders optimize storage solutions based on application requirements, all while aiming to minimize long-term costs,” he noted.
He also dismissed the idea of a competition between SSDs and HDDs, instead highlighting that the overall data storage market is growing, creating ample space for both technologies. “In the data center, SSDs and HDDs are not fighting over a fixed pie. The pie is growing rapidly as data storage demand continues to soar,” Azzi remarked.
AI’s Impact on Storage Demand
Azzi identified the AI-driven data cycle as a significant factor driving the demand for storage. AI systems generate vast amounts of data that need to be stored efficiently, and HDDs play a critical role in this ecosystem by handling both the ingestion of raw data and the storage of AI-generated content. “This dual role positions HDDs as a linchpin in the AI-driven data cycle, ensuring that data is available when needed and stored with the lowest TCO,” he said.
Citing Western Digital’s analysis, Azzi highlighted that HDD exabyte shipments are expected to grow at a compound annual growth rate (CAGR) of 30% between 2023 and 2027. He noted that the rise of AI, big data, and cloud technologies will continue to push storage requirements higher, making HDDs an indispensable tool in data management.
The Cloud and Data Growth
Azzi also pointed to the increasing role of the cloud in data storage. “Virtually everything today, from social media to enterprise systems, is powered by the cloud,” he said. This shift has led to massive volumes of data being moved to cloud environments for storage, processing, and analysis.
Quoting IDC data, Azzi stated that global data creation is projected to increase from 132.4 zettabytes (ZB) in 2023 to 393.9 ZB by 2028. While not all of this data will be stored, Azzi pointed out that around 13.6 ZB will be stored by 2028. He emphasized that “approximately 85% of enterprise data is still stored on HDDs, and this percentage is only expected to decline slightly over the next five years.”
Innovations in HDD Technology
Recent advances in HDD technology, according to Azzi, are helping to solidify the role of hard drives in large-scale data storage environments. With technologies like conventional magnetic recording (CMR) and shingled magnetic recording (SMR), HDD capacities have reached new heights—up to 26 terabytes (TB) for CMR and 32TB for SMR.
“These capacity advancements enable organizations to optimize their storage infrastructure for lower TCO,” Azzi said. He illustrated the cost-saving benefits by citing the example of a data center needing 192 petabytes (PB) of storage. By utilizing 32TB HDDs instead of 24TB models, the data center could reduce the number of racks needed from eight to six, saving both physical space and cutting TCO by up to 25%

In addition to lower TCO, Azzi mentioned that businesses are increasingly focused on environmental, social, and governance (ESG) goals, making efficient, high-capacity storage solutions a priority. “High-capacity HDDs can reduce physical footprints and energy consumption, making them a key part of meeting sustainability targets,” he added.
The Future of Data Storage
Looking to the future, Azzi stated that industries generating massive amounts of data, such as media, healthcare, and financial services, will continue to rely on HDDs to meet their storage needs. “As data continues to grow exponentially, the role of HDDs will only become more critical,” he remarked, underscoring that HDD innovations will keep pace with rising data storage demands.
Azzi affirmed that the demand for scalable, efficient data storage solutions will only intensify. “HDDs, with their unmatched capacity, efficiency, and cost-effectiveness, are well-positioned to remain the backbone of data storage for years to come,” he said.
In a world where data is growing at an unprecedented rate, Ghassan Azzi’s insights underscore the ongoing importance of HDDs in providing businesses with the scalable, efficient storage they need to navigate the challenges of the digital age.
