travelmate 8104 - comparison HDD 5400/7200 benchmarks

hi everyone!
had the hitachi travelstar 7200 at home form my old notebook - so decided to find out how much the performance difference would be. i mirrored the hdd image from my 8104 to the hitachi drive using norton ghost 9. i use the original installation with the stock driver.
i also wanted to find out if undervolting using rmclock would cause a performance loss - so i did tests with and without undervolting.
i used sisoft sandra, pcmark04 and hd tune to get comparable results - so here they are:

after all those tests i seams clear that the harddrive is no bottleneck in the system. it nearly works as fast as the 7200 rpm drive, is cooler and quieter aswell. my decission is made - i stick to the original 100gb hdd.
other than that is seems like that undervolting the cpu does cause a reduction in speed of the cpu und memory bandwith - it's not very big but it exists. i'm still sticking to undervolt my notebook vor it runs an average of about 10c° cooler under full cup load - that's worth it for me.

hope this answers some questions
greetings

glad i could help!
under normal workload, office programms, surfing etc, on an undervolted laptop with rmclock on automatic managment the fan comes up every 8 - 10 minutes for 2 - 4 minutes. that's at least my heat'n noise experience..
but as it looks to me - all the notebook with comparable capabilities have the same problem with heat - if i ever find out about a notebook that doesn't - i'll buy it
