Here's the thing most explainers skip: that internal air isn't just "kept clean," it's engineered. Traditional HDDs are filled with filtered, dry air at roughly atmospheric pressure because the read/write head relies on aerodynamic lift from that specific air density to fly at the correct height — too thin an atmosphere and the head flies too low or crashes; too thick and it flies too high to read reliably.
GPU acceleration is limited by the fraction of your workload that's actually parallel. Amdahl's Law states: if 90% of a program can be parallelized, the maximum speedup from infinite parallel processors is 10× — not infinite. The 10% sequential bottleneck always limits total speedup. In GPU-accelerated ML training, the actual workload split is typically: 85-95% embarrassingly parallel tensor operations
