## AI overview

This article recaps a POSETTE 2026 talk about how storage performance affects PostgreSQL workloads at scale. It describes a benchmark comparing a 3.3-billion-row workload on gp3 EBS and local NVMe, covering ingestion, read latency, autovacuum, checkpoints, and logical replication, and introduces production patterns for running PostgreSQL on local NVMe.
