  Nope. Accessing the disk, even when cached by the OS, is always very very
much slower than accessing a memory location (given that it's not swapped to
disk, of course). Of course the disk cache makes the operations a lot faster
in the average (compared to the case where each disk read really reads data
physically from the disk), but they are still very much slower than a direct
memory access.
