Solid state drive (SSD) specs often quote typical latencies—the time required by an SSD to fetch data requested by the system. But typical isn’t always representative of your workloads. You also need consistency.
Think of latency as the wait time at your favorite coffee shop from the moment you walk in until you get your beverage. Sometimes no one is waiting in line, and you get your drink almost immediately. That’s low latency. But at other times, you’re sixth in line, and those before you have complex beverage orders. You could wait for many long minutes. That’s high latency.
