### AI overview

Dropbox describes how long-running infrastructure optimization helps it accommodate growing AI demand by improving forecasting, fleet utilization, storage density, hardware lifecycles, and rack-level power delivery. Its storage infrastructure has used more than 50% less power per petabyte since 2020.

### Source excerpt

Dropbox has outlined how a decade of infrastructure optimization is helping it absorb growing demand from AI without treating new data-center capacity as the only answer. Its work spans forecasting, fleet utilization, storage density, hardware lifecycles, and rack-level power delivery, much of it predating the current AI boom. By Matt Foster

### AI overview

Dropbox describes how it improved storage efficiency in Magic Pocket, its exabyte-scale immutable blob storage system. A change that reduced write amplification increased fragmentation and storage overhead, so the team introduced a layered, adaptive compaction pipeline along with stronger monitoring and controls.

By turning compaction into a layered, adaptive pipeline and strengthening our monitoring and controls, we made Magic Pocket more resilient to workload changes.
