This text explores the global data explosion, projected to reach an astounding 181 zettabytes by 2025, largely driven by Artificial Intelligence (AI). It details earthbound storage technologies, including Hard Disk Drives (HDDs) for mass capacity and cost-effectiveness, and Solid State Drives (SSDs) for high performance (leveraging NVMe and PCIe interfaces). Cloud storage is presented as a paradigm shift, offering scalability and agility, alongside the growing market for external storage devices. Essential data management techniques such as RAID for improved performance and reliability, and the 3-2-1 backup principle for disaster recovery, are crucial. System development emphasizes effective data organization, compression, and encryption for integrity and security.
The discussion extends to the booming space economy, valued at $400 billion in 2023, with satellites accounting for 71%. New Ground Computing, which tightly integrates space (e.g., LEO satellites) and ground (cloud and edge AI) technologies, is vital for real-time data processing and analysis. AI and Machine Learning (ML) are transforming satellite image analysis, disaster warning systems, and smart operations. Major challenges in space include high costs, launch risks, space debris (Kessler syndrome), complex international legal and policy issues, space militarization, and unproven commercial markets. These advancements highlight the intertwined relationship between data storage/management and space exploration.
