Problem
A NAS has sufficient aggregate bandwidth but inadequate IOPS for simultaneous proxy generation, waveform analysis, and database access.
Solution
Root Cause / Diagnostic:
Mechanical hard drive NAS arrays excel at high sequential read/write bandwidth, but deliver low random IOPS (typically 75–100 IOPS per disk). Running concurrent operations—such as batch proxy generation, waveform rendering, and PostgreSQL database queries—destroys sequential head movement, causing timeline playback to stall completely.
Actionable Fix:
1. Multi-Tier Workload Segmentation: Add a dedicated high-IOPS NVMe flash pool on the NAS for proxy generation and database hosting, reserving the mechanical RAID pool for sequential master media playback.
2. Sequential Workflow Scheduling: Schedule batch proxy generation and waveform analysis during off-hours or export them locally before moving completed files to network storage.
3. IOPS & Queue Depth Telemetry Audit: Monitor disk latency and queue depth via NAS CLI (`iostat -xz 1`); ensure disk wait times remain under 10ms during editing sessions.
Pro Tip:
A hard drive array can stream huge video files easily, but generating waveforms and proxies creates thousands of tiny random reads that choke mechanical disks; do heavy proxy rendering on an SSD.
