Is there some faster way than /dev/[u]random? Sometimes, I need to do things like

cat /dev/urandom > /dev/sdb

The random devices are "too" secure und unfortunately too slow for that. I know that there are wipe and similar tools for secure deletion, but I suppose there are also some on-board means to that in Linux.
