I'll give dd a try; but I don't see offhand why
dd if=/dev/urandom of=/dev/sdc bs=1M

shred -v -n1 /dev/sdc
I don't know how it generates the data to overwrite with. Does it use a
lot of CPU? If not, then dd will probably not be faster, you might be
at maximum speed for the drive. However, shred is intended for files,
not partitions.
