When NVMe SSDs Beat More HBM for LLM KV Cache—and When They Don't
Offloading LLM KV cache to NVMe SSDs provides substantial capacity and cost advantages for high concurrency and long contexts, but it comes with a notable latency penalty. The decision hinges on workload latency tolerance, concurrency needs, and context length.
