Growth Drivers

• Data growth and expansion of data centers: The volume of data generated globally is growing exponentially due to digital transformation across healthcare, retail, and entertainment sectors. The rise of IoT, 5G, and social media fuel this data explosion, as billions of connected devices create vast amounts of information daily. For instance, there were 16.6 billion linked IoT devices by the end of 2023 (a 15% increase over 2022), and this value climbed 13% to 18.8 billion by the end of 2024. This unprecedented growth in data requires robust storage solutions. Although SSDs are increasingly popular for high-speed applications, hard disks remain essential for high-capacity and cost-effective storage, especially for cold storage or archival purposes, where retrieval speed is less critical.
  
  Data centers support global cloud services, artificial intelligence, big data analytics, and digital transformation initiatives. The demand for reliable, high-capacity storage is increasing with the rapid growth of cloud providers and hyperscale data centers. Hard disks are favored by data centers for bulk storage due to their cost-per-gigabyte advantage over SSDs at high capacities.
• Emerging markets and digitalization: Many emerging economies are investing heavily in digital infrastructure as they digitize services in government, healthcare, education, and finance. This transformation is driving demand for data storage solutions to support the data-intensive requirements of these sectors. Hard disks are preferred in these markets due to their cost-effectiveness, making them ideal for large-scale data storage needs where budget constraints may limit the adoption of more expensive storage options.
  
  Moreover, increased internet penetration, mobile connectivity, and the adoption of smart devices in emerging markets are leading to an exponential increase in data generation. With more users online, data volumes are growing rapidly, particularly in social media, e-commerce, streaming, and e-learning, all of which require reliable storage infrastructure. For instance, about 33% of the world's population shops online, representing a 2.7% growth from 2023.
• Video surveillance and security: Surveillance systems are increasingly using high-definition and 4K cameras to capture clearer, more detailed footage. This higher-quality video generates larger file sizes, which require substantial storage capacity, making hard disks an ideal solution due to their cost-effectiveness at large capacities. Additionally, as security installations expand from critical infrastructure to residential and retail spaces, storage requirements continue to grow, driving demand for high-capacity hard disks.
  
  Governments around the world are investing in smart city initiatives, which often include extensive surveillance systems for monitoring public spaces, managing traffic, and enhancing urban security. For instance, according to the U.S. Bureau of Labor Statistics, surveillance camera installations in the U.S. increased by 21%, from 70 million in 2018 to roughly 85 million in 2021. These initiatives are especially prevalent in emerging economies and large metropolitan areas, where robust, reliable storage solutions are required. High-capacity hard disks play a critical role in supporting these smart city projects, offering scalable storage solutions that balance performance and cost.

Challenges

• Increasing competition from solid-state drives (SSDs): SSDs have gained popularity due to their superior speed, energy efficiency, and durability compared to hard disks. This shift is particularly strong in the consumer and enterprise sectors, where speed and performance are highly valued.  As SSD prices continue to fall and capacities increase, more consumers and enterprises are adopting SSDs, especially for applications that prioritize performance over capacity, such as laptops, gaming, and high-speed data processing.
• Energy consumption concerns: Hard disks generally consume more power, which has become a growing concern as data centers look to optimize energy efficiency and reduce operational costs. High power consumption translates to higher cooling and electricity requirements, making hard disks less attractive for companies focused on sustainability. With the increasing pressure on data centers to reduce their carbon footprints, SSDs are often preferred over hard disks for low-power, high-efficiency storage needs.
