Unlock PostgreSQL’s True Performance with Local SSDs
Wednesday, October 22 at 14:45–15:35
Cloud storage was built around the limits of old hardware. Spinning hard drives (HDDs) were slow and fragile. So, early on, cloud providers moved storage off of servers. They used network-attached disks to boost durability and scalability. But hardware has evolved. Today, you can get 2.5 million IOPS from a $600 NVMe SSD. Achieving the same throughput through network-attached storage in the cloud can cost hundreds of thousands of dollars per month. With NVMe SSDs now faster, cheaper, and more reliable, it's time to rethink PostgreSQL storage.
In this talk, we’ll walk through different disk architectures and their impacts on PostgreSQL performance, how we got here, what’s changed, and why local NVMe SSDs are the future for PostgreSQL storage. We'll also share benchmarks comparing performance on different disk architectures and share results from real life case studies.
