About:
HDF5 is a high-performance data management and storage suite. It features a versatile data model that can represent very complex data objects and relationships. Its main value proposition is enabling efficient, scalable I/O for scientific computing and big data applications.
Key Features:
  • High-performance I/O for large datasets
  • Portable file format with robust data model
  • Supports parallel I/O (MPI)
  • Extensive language bindings (C, C++, Fortran, Python)
Use Cases:
  • Storing and accessing large-scale scientific simulation data
  • Managing multi-terabyte satellite imagery datasets
  • Archiving and sharing research data
Alternatives:
  • NetCDF – Built on HDF5, adds climate/science conventions; similar performance but more domain-specific
  • SQLite – Relational database engine; better for transactional data, less efficient for massive binary arrays
  • Zarr – Cloud-native chunked arrays; better for cloud storage and parallel cloud access, HDF5 better for HPC filesystems
