Generally true, but with exceptions: a 2.5" HDD draws approx.
4 Watts, and you can reduce overall consumption by spinning down
OTOH, a Flash drive doesn't draw that much power when idle or
when read, but when writing, it is substantial (and slow). A
RAM-based SSD has yet another power profile...

And to get ever more OT: my biggest gripe with current laptops and
netbooks is that it is usually difficult to find external batteries,
that you could either strap on or below the box (in parallel
switching) or that you could hot-swap easily without having to shut
Even a bigger external battery that you could plug into the DC input
would be good enough for most uses, but you'll have to DIY, as you
won't find an easy on-the-shelf solution in your electronics store.
I don't mind if the internal battery lasts only 90-150 minutes, as
long as I can easily swap it with the spare batteries or an external
battery that I'd carry in my backback. If you need at least 8-10 hours
(or even more) of continuous autonomy, that's pretty important, IMHO.
