Yes... they can.

No... I haven't tried it.

Some random memory engram of mine recalls, a link on Slashdot somewhere,
which pruported a person had used an array of ipod switchers as hardware
for just such a raid setup.

/motivates self to look.

nope... can't find it. Either I hallucinated it, or my google search
terms don't cause a hit.. In any case the theory is sound... since your
usb storage media, will simply end up being called /dev/sdxy in terms of
Linux (or *BSD probably) you can easily use sdxy devices for raid.... be
those devices usb, firewire, /real/ hard disks... in fact, you could
even *mix* different types of storage media... though you might find,
that theory!=practice.

Alsoooo, it's worth noting that you can't write indefinately to flash
memory... whereas... traditional hard disks you /can/... barring, some
sort of actual disagreeable hardware event like gravity + harddisk +
concrete floor.
