# Fast Writes Only Move the Work Elsewhere

A common engineering adage notes that optimizing for fast writes simply relocates the workload to another phase, such as reads, background compaction, or consistency enforcement. This trade-off means that improving write latency often increases complexity or costs elsewhere in a system. The insight matters for architects balancing performance, reliability, and operational overhead.

**Importance:** 3/5
