Hard drive access speeds are infinitely slower then main memory. Main memory accesses in "nanoseconds" and HDD`s access in "milliseconds". To a CPU that executes instructions at say 700mhz is executing 700,000,000 cycles in one second. There is no way for "mechanical" memory to access this fast. However, the HDD we use today may well give way to "solid state" drives in the non to distant future. This is available today but at a substantial cost.
