WD Scorpio harddrive = Better battery life

[5p33d0]

Could not find a thread that talked about this.

Since I started using a WD 250gb as my main hd i have gained an approx 1~2 hours life depending on wifi and other factors on my extended battery.
Cant say about regular battery as mine lasts only one hour and haven used it yet with the WD

Anyone else has noticed this?

Interesting information, but I feel we miss a bit of information here: You compare the performance of your new Western Digital WD2500BEVE against your old drive - but you don't tell what the old drive specifically was? Also, did you change anything (anything?) except the drive? You didn't also swap the battery or alter some settings?

According to the WD2500BEVE datasheet its power consumption is:

Current Requirements (@ 5 VDC)
Read/Write 500 mA
Idle 400 mA
Standby 60 mA
Sleep 60 mA

Power Dissipation
Read/Write 2.50 Watts
Idle 0.85 Watts
Standby 0.30 Watts
Sleep 0.30 Watts

... so this is what you need to compare to your old HDD.

Questions: Have you noticed any clicking sound (/"noise") from the WD HDD? Would you say is is "inaudible" or slightly noisy? Many users have reported it... but it might been cured by the newest drives?? Also, how hot do you feel the WD2500BEVE runs? Different from your old?

I don't think the WD alone would cause such as huge increase in battery life.

Ahh good point.
in my haste and excitement i didnt mention details.
It was an unexpected benefit.

my thinkpad is a t40 with no internal wifi - i use a PC card
Upgraded to:
1.7 Dothan
2gb ram

old HD: 5400 rpm 80 gb Hitachi - (who has the power consumption data?)
Battery life - 5 - 5.5 hours on the still new extended battery.

New: 5400 rpm 250 gb WD
battery life - ~6.5 hours on the same battery.

No changes to settings.

My settings are always lcd brightness on ZERO.
low CPU profile.
I pull out the card to turn off wifi when not in use.
DVD rom - disabled from Device manager.
One PC card slot disabled
old style printer port disabled
Modem disabled
Ethernet Disabled

Laptop use:
OneNote 2007 with microphone recording. wifi off.
Web browsing periods. wifi on

also add ina few applications like Paint and Notepad
Openoffice 3: Draw and Formula


Questions: Have you noticed any clicking sound (/"noise") from the WD HDD?
No noice- only this woosh sound when reading- noticeable in empty room

Would you say is is "inaudible" or slightly noisy?
inaudible- unless ur picky

users have reported it... but it might been cured by the newest drives??
My drive came in celophane from www.canadacomputers.com
How can i find manufacture date? My driver infor says its a 2001 driver

Also, how hot do you feel the WD2500BEVE runs? Different from your old?
Windows XP Sp3 is FAAST. Very satisfied.
Typing feels more real-time then ever. Nvr thought i would say that.
net- browsing is fast. Firefox 3 .. latest stable rel
in general windows all of them open real fast.

I defragged before the re-image from old drive and defragged after new HD was working.

Like i said very satisfied this smokes my HP dv6xxx laptop with an athlon x64 with vista in responsiveness.

Any other questions please ask.
