Question ID: 240113
I am looking for a comparison of the difference in power consumption
between different capacities of laptop components (and some desktop
components) and peripherals:
Hard drives (rpms 4200 vs. 5400) vs. 7200 for desktop
RAM different capcities from 32MB, 64MB, 96MB, 128MB, 256MB
Laptop LCDs: 10 inch, 12 inch, 14 inch 17 inch
Exernal CD drives: 10x, 24x, 52x
Compact flash cards
Network cards

Specific data must be hard to find, or someone would have jumped on
your $50. My guess is all those items are in the 1 watt to 20 watt
range/ unimportant for a desktop, but 20 watts runs down batteries
fast. I have no idea for flash cards nor network cards. Power needs
likely doubles from the least to the most. but will also vary about
that much from brand to brand and model to model, with the newest
typically using no more power inspite of some performance
improvements.  Sorry I can only guess.  Neil

Desktop disks run ~<10W idle.  Laptop drives won't be hard to find
RAM is the same for laptop and desktop applications (DDR uses less
power than SDR)
LCDs might be entertaining to find - the original manufacturer should
have datasheets available.

External CD drives?  Of what sort?

CF cards have maximum power draw defined by the spec (IIRC).
NICs will be very hard to find.  I assume you mean PCMCIA/PC-CARD NICs
v. PCI NICs?  100Mbit?  GigE?

I'll devote a bit of time to this when I have more steady bandwidth
(on a tenuous 802.11b link right now); would you accept as an answer
everything on your list sans the NICs?

Yes - I am talking about PCMCIA 100MBit ethernet NICs.  I would be
more than willing to accept a well defined answer without this item.

Thanks,

Mark
