I've run into PCs whose USB ports don't really supply the full nominal
USB power voltage (500mA). A USB2 drive housing I have here comes up as
USB1.1 unless I use a powered hub or external power supply for the drive
housing.
Also, older notebook hard drives can quite easily use 500mA just for the
drive - leaving nothing for the interface circuitry. And housings for
bigger drives (3.5" drives, for instance) almost always require an
external power supply. You can usually find out how much power a hard
drive requires by checking the manufacturer's label.

I have Vantec NexStar SX enclosures for my old laptop 2.5" IDE
hardrives. I haven't used those drives for recording (yet, but i
don't really use my computer for recording) but I have been happy with
the performance. And they can be USB powered, too. The only drawback
is that the aluminum is high-polish and fingerprints appear as soon as
you take it out of the wrapper. They come with USB cable that has a 1
port hub attached, 4 screws for your hd + a mini screwdriver and a
leather-like case. I think they are a good deal for ~$20.

USB 2.0 is plenty fast for recording audio tracks. you should not have
a problem with that at all, assuming it's a good disk and the system's
USB implementation is done correctly.
Just mount the drive and run hdparm -tT to get an idea of the drive's
speed. I'm sure it will be fine.

mark, very much thanks for the response!
i think i ll go for a combination of an ata-laptop-drive, with this
usb-case-adapter for it.
that seems cheap, and i do not need an extra power chord for the
external drive than - which is important for me, since everything runs
on solarpower, 12Vdc here.
cheers,
doc
Sounds nice not to have the power cords. I've got 3 Firewire drives
and often get tired of all the power connections. Each drive has a
different power supply and I've got to get them matched up correctly.
A small drive that gets power from the bus would be far nicer for fast
setup and tear down.
Good luck.
