You can do it with a shell for loop:

for i in {1..20000}; do dd if=/dev/urandom bs=1 count=1 of=file$i; done

Adjust count and bs as necessary to make files of the size you care about. Note that I changed to /dev/urandom to prevent blocking.

You can add some >/dev/null 2>&1 to quiet it down, too.
