You can wipe your drive with:
dd if=/dev/zero of=/dev/[device to be wiped]
followed by:
dd if=/dev/urandom of=/dev/[device to be wiped]
repeat 7 times per device if you want the DoD standard for wiping a drive. If you would like to save time/trouble drop the sequence in a script. Plenty of examples on the web. One pass is usually good for most ppl tbh. Though I did do a recovery once that rebuilt the last 3 OS installs on the server... but if you trust the person you are giving them too not to care then one pass should do.

The quickest would be to encrypt the drives from the beginning. When you
want to discard the drives, you just need to wipe the LUKS header. With
the key wiped out, the rest of the drive is just random bits.
