Solid State HD

They could be mainstream by now if it wasn't for the extreme bloat of
"modern" software.
I'd thought that a really small low power HD, say 1G for the OS, and
another flash drive might be a short term solution

It would, if we'd all use legacy software. Which BTW would be just fine
with me. Back in the late 80's I was able to do almost anything in
engineering I do now, on HDs in sizes ranging from 10MB to 40MB (I never
even went past 30% capacity on the latter). Yes, including the
generation of fancy module specs with schematic sections, SPICE plots
and analyzer plots in there.

But now many files won't even fit onto a 1.44MB floppy anymore.
Unfortunately we have to howl with the wolves here because we must be
able to read other peoples docs. Personally I tend to stick with the old
simple ways for stuff that remains local. For example, the complete set
of business records for one tax year is well under 1MB. And this
includes lots of database entries beyond what the law requires so should
there ever be an audit I can find stuff for them within seconds.

Unfortunately, low density HD are not at all low power/noise. They
are usually older designs. Noise is annoying. My 5G laptop drive is
as noisy as a desktop drive. I replaced it with a 1G Flash drive.
Now my laptop is absolutely quiet. All my AVR developement tools fit
in 1G, including X11/WINE. It also run out of solar charged
batteries, for field developments.

This 15V toshiba laptop was included with a 18V compaq adapter. As
expected, the power regulator, Li-Ion batteries are all fried.

How? Did you put it inside and hardwire over to it from a USB port?

The Labor Day sale flyer for K-Mart lists a 1 GB PNY USB jump drive
as being on sale for $9.99 from Aug. 30 to Sept. 3.

Sure. But that doesn't make the file sizes small and efficient again ;-)

Again, most old laptop can't boot from USB.

This is a Toshiba 233MHz Pentium.

The CFD drive fit inside the space on the top left corner. The 1.5A
switching regulator is next it. The original laptop came with a 4A
power adapter. This setup is running cooler than my cable box (hot)
and PS3 (very hot) next to it.

Probably you get a lot longer battery life out of it now (if you'd
replace it's shot battery).

If I take out the CDROM and Ethernet PCMCIA card, it should be less
than 1A @12V. The S3 video chip is hotter than the Toshiba CPU
(probably a custom mobile Pentium). I might be able to switch power
to the video chip. One of my customer wants it to run directly on
solar panels, no other power available.

12 watts is still a lot. IMHO the best in terms of economy were the old
Compaq Conturas. Mine ran up to 6hrs on a single NiCd charge. To me
anything that came later looked like a step beck in power economy.

It measured 0.6A average, so about 6W or 9 hours on the 4.4Ahr
battery. But this is without the CDROM and LCD screen.

Well, yes, but a PC ain't much use when you can't see the screen ;-)

I've a 100 gig Seagate in my laptop and it is very quiet. Too bad the
thing has two fans that rev up when under load. I'm running Kubuntu Edgy,
KDE version of Ubuntu.

Well, it's an embedded laptop.

Yes, we do need to plug in an external LCD monitor once in a while.
But other than that, we only need a WiFi card for quick data dump.
There is an USB data logger attached to the embedded laptop. The USB
data logger takes another 10 to 20mA.

The USB data logger listens to remote devices transmitting a simple RF
data modulation (probably AM band). We need less than 100 bits per
second. But this is still further down the line of developments.

But we don't want to put these $100 drives on $50 laptops. There are
plenty of 200MHz laptop for less than $50 on ebay.

If you have any say in this try to steer away from AM modulation. The AM
band is ok if you stay legal, just not as a modulation scheme for data.
