Question 5

An astronomical observatory operates a radio telescope array generating terabytes of raw telemetry data daily. The facility requires storage solutions for two distinct functions:

  1. Real-time processing, filtering, and calibration of incoming high-frequency streams.
  2. Decades-long archiving of the raw signal logs for retrospective scientific research.

Evaluate the suitability of Solid State Drives (SSDs), Hard Disk Drives (HDDs), and Magnetic Tape for these different operational requirements, justifying which media are best suited to each task.
