Write random data to a disk, quickly

openssl enc -aes-256-ctr -pass pass:"$(dd if=/dev/urandom bs=128 count=1 2>/dev/null | base64)" -nosalt </dev/zero | pv --progress --eta --rate --bytes --size 8000632782848 | dd of=/dev/md0 bs=2M
Due to @tremby, here: http://unix.stackexchange.com/a/172088/58343. I'm looking for a way to parallelize openssl and feed that to dd since openssl is the bottleneck on my machine: http://unix.stackexchange.com/questions/253466/parallelize-openssl-as-input-to-dd

What Others Think

Hi, great question, I also asked it when I was just starting to study for an MBA, so check this educational source which helped me to find and learn a lot really useful information. Perhaps it will be as useful to you as to me.
