You'll want to check the power figures on that Compact Flash as well. At least if power consumption is a concern.
The data sheet Flandry linked indicates 500 m amp @ 5 volts. That's 2.5 watts - simular to a laptop drive. You'd also have to consider the adaptor's power consumption, which I don't have a clue what they would consume. Maybe next to nothing? Maybe a watt or two?
You can see both in the data sheet for the Transcend SSD and in the power test results that the SSD erased most of the Travelstar's power consumption. Admittedly, though, at a loss in both space and speed.
There's really no reason for a CF form factor to take more power than a SSD. If anything, i would expect it to draw less. I think the only difference between the SSD and the 266 card is that the SSD uses slower chips -- it's comparable with the 133x or maybe even a slower card offered by Transcend.
Anyway, the adapter has 0 power draw--CF is an ATA device that simply needs a suitable connector. There is nothing but wires in the adapter.
Addonics makes adapters that plug directly into a laptop PATA connector and fits right into a laptop, in fact, they make an adapter that takes two CF cards. Here's
a review of the basic adapter.
