L1, L2, RAM and HDD Latencies - Infographic

I stumbled upon this infographic that illustrates the latencies in L1 cache, L2 cache, RAM and HDD. Each pixel represents 1ns - you will need to zoom into the top of the image to see the detail.

In summary:

L1 Cache (1ns)
L2 Cache (4.7ns)
RAM (83ns)
Hard Disk (13,700,000ns)
