The RAM stores the data to be executed by the computer. Memory generally runs as fast as the bus speed of the computer, which in your case is 533MHz. The hard drive runs off of the PCI bus, which is 33MHz. The theoretical maximum read speed of your ATA100 hard drive is 100MB/sec...whereas your PC800 RDRAM runs at 1600MB/sec. If a computer becomes low on RAM during intensive application cycles, the computer can perform an operation known as "swapping". When this occurs, the computer temporarily uses hard drive space as additional memory. Constantly relying on this type of backup memory is called thrashing, which is generally undesirable because it lowers overall system performance.
