Waste signals
- PDs detached > 7 days
- SSD on cold data
- Snapshots beyond retention policy

Persistent Disks persist after VM deletion. TurboFinOps inventories disk attachment state and right-tier recommendations.
Typical savings range$200-$3,500 / monthGCP project with 500+ disks
Optimization levers
- Delete unattached disks after cooldown
- Downgrade pd-ssd → pd-balanced for cold data
- Prune stale snapshots
