Local NVMe SSDs: The Future of Cloud Databases?
2025-06-02
Cloud storage was initially designed around the limitations of older hardware, using network-attached disks to enhance durability and scalability. However, today's cost-effective NVMe SSDs offer significantly superior performance. This article demonstrates that PostgreSQL databases using local NVMe SSDs outperform AWS RDS and Aurora by several times in TPC-C and TPC-H benchmarks. While network-attached storage retains advantages in elasticity and durability, the reliability and affordability of NVMe SSDs now largely compensate, making local NVMe SSDs a compelling future for cloud databases.
