Fastmail: Why We Stick With Our Own Hardware

Fastmail, with 25 years of experience running its own hardware, details why they choose this approach over cloud services. Through careful hardware planning, in-house operational expertise, and maximizing hardware lifespan, they achieve significant cost optimization. From initial SAS and SATA drives to current NVMe SSDs and the ZFS filesystem, Fastmail continually upgrades, leveraging Zstandard compression for increased efficiency and reliability. A cost comparison of cloud storage, HDD upgrades, and building NVMe SSD servers led them to choose the latter for superior reliability, performance, cost-effectiveness, and the ability to fully utilize their internal network.
