Latency is what makes Optane impressive. Queue depth 1 is where you still feel latency. When you read a file… that points to other files to read… that points to other files to read… and so on. The really staggering comparative example of this is launching something like 20 beefy desktop applications at the same time. Even though it’s sequential throughput is only 40% at best of other competitors, it’s where Optane blows the absolute doors off everything else. When SSDs get to sub-10us latency, that’s when it’s really party time.
