PlanetScale Metal: There’s no replacement for displacement

This post introduces PlanetScale Metal, a new offering that replaces network-attached storage (like Amazon EBS and Google Persistent Disk) with fast, local NVMe drives for MySQL-compatible and Postgres databases. It details the performance and cost advantages of local NVMe drives over network-attached storage, citing specific IOPS and latency improvements. The post also explains how Metal maintains durability through semi-synchronous replication and tested backups, and provides a cost comparison showing Metal's superior IOPS per dollar.
