Dunno about the differences - that I have an x64 OS might matter somewhat (it has somewhat more efficient system calls and context switching than x86), that I run x64 CrystalDiskMark shouldn't matter much. We're probably using roughly the same speed RAM (same MHz, timing might be different but I haven't seen that matter
that much in recent years).
Raymond doesn't mention which CPU he has, which
does matter, since cache size and memory controllers differ - given that he runs DDR3 ram, I do assume his CPU is modern enough that the memory controller is on the CPU and not the motherboard chipset. He also doesn't mention NTFS cluster size, but that's probably going to be standard 4k, and I don't know how much that really matters, outside of how it affects fragmentation.
The most interesting differences are definitely in the 4k results. It might be something as simple as me having a faster CPU? (One core seemed to be maxed out during a fair amount of the test). At ludicrous speeds like that, and a small size like 4kb, there's probably going to be quite a few context switches per second
