Ok, so I have a friend of mine here who wont take my word for this fact:

As per him:
Copy speeds are dependent on processor in the system. So a P-4 copies slower than a core2Duo, hard disk remaining constant
I didnt even want to get into the whole debate as to how DMA chips and everything comes into play to make the copying not dependent on the CPU.
Replies/Links appreciated since google doesnt give me relevant stuff (maybe my query is wrong)
 
p3 upwards, proc doesnt play much role. so u r right, its the dma/ pio mode, chipset, interface capability and the actual device that dictate the speed. the slowest of any of these devices is the actual speed you can see. in dma, the prccy is bypassed and the system bus itself takes over the data transfer operation. in PIO it is cpu dependant. read any 80386 manual (intel - avail in engg. colleges) to provide more details to ur friend.
 
also depends on the SATA chipset used. older gen chipsets were slow so probably a P4 mobo with an old SATA chipset will actually copy slower :P and you'll have to accept defeat :lol:

I did say all else being same. The chipset n the proccy are diff things.
