Yep. Most programmers today don't realize that "R" in "random access memory" can turn your RAM into a pumpkin very easily, and reduce bandwidth to below what you can get reading sequentially _from a budget SSD_.

Another number to put things into perspective: at 4GHz, 60ns is _240_ cycles. So every time you feel like you don't care about cache locality, try laboriously counting to 240.
