Is the original 770X 8GB HD *that* inefficient?

I recently replaced the original 8GB Travelstar drive with an 80GB Samsung drive that I acquired and find that I can maybe get another 30 minutes of battery life (2:30'ish vs. a shade over 2 hrs). Are the older drives this bad in terms of power usage or is this just a fluke?

One other thing about the newer drive--can't even hear it. The older drive literally sounded like a jet engine compared to this one.

The new one is a 7200 or 5400 drive?

[catnap1972]

New one is 5400 RPM

New one is 5400 RPM

I got the same drive in my T40, man that sure is a great drive silent and very energy efficient.

When i replaced the "enourmous" 4gb drive that my 600x came with a 7k100 100GB it added 45 minutes more to battery life.

So my opinion is that the original drive may not be that bad just that the newest are more efficient. Example the cache from your new drive is 8mb the old one had like 1 or 2mb. More cache means than less rotation is needed for your drive to find the info.

I put a Toshiba 80GB 5400RPM drive in my 600E and got upto 3 hours when I could only *ever* get 2 and 10 mins at the most...

I use the extra time to kock the brightness up a bit as the backlight in mine is a bit... knackered

SO it is proven if you want more battery life, one option would be replacing you hardrive with a newer one that is more efficient and that runs at 7,200rpm or 5,400rpm 8mb or 16mb cache.

depends how the drive was set with feature tool program.
but it doesn't surpise me with 5.4 or 7.2 k drives as i have not seen them use more battery in the first hand.
samsungs are the best laptop drives going.($spent)
tp 600e gets up to30mps max sustained speeds
tp600x gets approx 28mps from their respective ata33 host busses.
thats on par with a well setup desktop running a seagate barracuda 11/30gb/ 7.2 k desktop drive running from a ata 100 (defaulted to ata66)host bus.
and about 20-25% faster tha a $4100 current spec packard bell
centrino 1.8 ghz laptop thats supposed to support ata 100 in the first hand.
thats why thinkpads rule.
work that out .
