Question 3

An autonomous freight logistics provider operating a fleet of self-driving delivery trucks is designing its data storage architecture. The company must store:

  1. Continuous, real-time telemetry and 3D LiDAR sensor data onboard the moving trucks, which experience high physical vibration and shock.
  2. Large batches of weekly log data at stationary regional depots for pre-processing and local analysis.
  3. Multi-decade archives of historical safety logs and incident reports for regulatory compliance.

Compare the suitability of Solid State Drives (SSDs), Hard Disk Drives (HDDs), and Magnetic Tape for each of these three requirements.
