its more dependent on the motherboard ( onboard ide controller chips )
- same disk will under-perform by 1/2 or more if a slow/bad ide driver on
the "bad" mb
- all else staying the same/unchanged
- don't get cheap mb... :-)
- other variables like cpu/memory ( cas timing )
- adding more memory didnt make the system compile any faster
- adding faster cpu didnt make the system compile any faster
( compile 2.4.19 was the test --- 5-6 minutes on average
( for p4-1.6 or p4-2.0 w/ 512MB - pc133 and/or
( amd-1700+ w/ 512MB PC-2100 ddr -- keeps up with a p4 system
