As TechTarget notes, while AI and hybrid multi-cloud strategies drive cost governance, the physical reality of <strong>disk I/O latency</strong> remains the ultimate bottleneck for database durability. Alasdair Brown&#039;s analysis confirms that the primary challenge in running <strong>Postgres</strong> is not the volume of bytes stored, but surviving the moments when the database must stop and wait for durable commits.</p>
