Well, it wasn't obvious from the posting that this device requires a
2.5" HD (assuming that's what you mean by laptop drive).
If that is the case, then yes, 2.5" drives are significantly more
expensive than 3.5" drives, indeed.

it wasn't??

which desktop drive fits in that space?

desktop drive on battery power? 270g ?

While I apologize for not being far more explicit, I didn't believe
that it was particularly necessary to do so, since the item of
comparison (an Atom Netbook) doesn't run off of a desktop 3.5" drive
either.

Since a specific product was named, one could have also tried a quick
Google before challenging. To be helpful, here's the relevant product
page which does explicitly state that it takes a 2.5" SATA:

<http://www.hypershop.com/HyperDrive-COLORSPACE-UDMA-Casing-Only-p/
hdcsu-000.htm>


FWIW, the battery power supply on the old Hyperdrive HD-80 that I have
consists of four (4) AA's ... the new Colorspace has replaced this
with a single 3.7v Li-Ion LG 18650 2600mAh battery.

FYI, it also appears that I erroniously quoted the specifications of
the previous "Colorspace" (not the current "Colorspace UDMA") model,
which results in some minor discrepancies.

Size: I said approx 5x3x1 ... exact values are: 5.25" x 2.95" x
1" (133 x 75 x 26 mm)

Weight: I had said 9.5/270gr...its now 10.5 ounce (298g)

GB transfer per battery charge: I had said 120GB ... its now 250GB.


All in all, its a pretty nice device for when it makes sense to
have. Its real niche is for when you want more capacity than your
[CF] cards alone, while also having weight (and/or power) limitations
that discourage a laptop/netbook type of solution. This isn't
necessarily a common problem, but it isn't an impossible one either:
I've run into it in bush plane flights on three continents.
