Yeah, I wouldn't do that, that graph is hardly accurate. 9ns won't get you a L3 cache hit on most skylake chips, nevermind main memory.
For sequential access giving a latency number doesn't make sense - you need to talk throughput. You can get upwards of 20gb/s with a single core for DRAM. Here you're at least bounded by the 4x PCI interface (more likely the Optane device) so maybe 3GB/s if you're feeling generous.
