Also the following command works fine for clearing the the disk with random data, it averages out at ~130MiB/s: openssl enc -aes-256-ctr -pass pass:"$(dd if=/dev/urandom bs=128 count=1 2>/dev/null | base64)" -nosalt < /dev/zero | pv -s "$(blockdev --getsize64 /dev/sdX)" > /dev/sdX (with sdX replaced by the correct device).
