Rethinking PostgreSQL Storage
Today, you can get 2.5 million IOPS from a $600 NVMe SSD. By contrast, pushing 2.5 million IOPS through Aurora would cost you $1.3M per month. With NVMe SSDs now faster, cheaper, and more reliable, it's time to rethink PostgreSQL storage.
Most database teams would buy specialized hard drives and put them into fancy RAID configurations to compensate for these problems. As we mentioned in the beginning, the cost of 2.5 million IOPS on Aurora is $1.3M/month, but you can achieve the same performance with a $600 local NVMe SSD. The cloud storage model built 15 years ago no longer makes sense for today’s hardware and workloads.
