Well... Let's say... Good luck.
I am experimenting raid1 and raid5 over firewire, which is by far much
more stable (in terms of bandwidth) than usb2. According to the tests
I made, benchmarking usb2 and firewire makes usb2 dangerous to use :
connection hangs, bus collision is somewhat hasardous, bandwidth is
not really granted.
Technically, it is really possible : you will have your usb2 drives
accessible as scsi drives, put your raid on them, test them. But
sincerely, good luck.
