The CFQ works well for many general use cases but lacks latency guarantees. The deadline excels at latency-sensitive use cases ( like databases ), and noop is closer to no schedule at all. For example, on a 128GB memory host, this can allow up to 38.4GB of dirty pages. Two other schedulers are deadline and noop.
