Default 2.5" disks?

I'm running a Sager NP 4750 laptop.

I wish to buy 2 2.5" (notebook) disks, one around 60 GB, the other 100+ GB (preferably quite a bit more). I would like to mount these disks in UNpowered USB cases. Therefore, if my understanding is correct, each drive must consume no more than about 450-500 mA to run on a typical powered hub drawing 1 amp through a power supply and additional power from the on-board USB.

1. Is my power estimate reasonable under the circumstances? (Ask more questions if needed !

2. Does anyone know who (manufacturer, other vendor) makes such drives that really do consume low power, at or below the target I've expressed.

3. Does anyone recommend a brand/model for the cases to put them in? I'm presently looking at the CPUE205 and CPUE215 (adds firewire) from CP Technologies (, but I'm totally open-minded.

4. Has anyone used the little USB hub (for its size, not its capacity) from the same vendor, model CP-UH-135? Other recommendations?

Thanks to all!
