IMPROVING INFRASTRUCTURE EFFICIENCY FOR GROWING DEMAND IN THE AGE OF AI

Summary from the TLDR Dev newsletter

Due to AI, Dropbox has optimized capacity planning, hardware, power, and cooling as one coupled system rather than just building more data centers. Its team has squeezed more from the existing fleet via Deep Sleep (spinning down idle drives and servers, recoverable in minutes), workload rebalancing so local hotspots don't trigger global capacity adds, and denser drives using shingled magnetic recording. They measure efficiency as watts per petabyte instead of total power draw, which has improved over 50% since 2020.
