HDD burn-in testing, or how i learned to fail fast and love the RMA

With compression on, dumping /dev/zero into a file probably wouldn’t do much, other than rapidly incrementing a few counters, wihtout actually writing. Afaik, /dev/random or urandom doesn’t have the throughput that might be desired.

You can use openssl to generate incompressible (effectively random) data much faster than /dev/urandom:

openssl enc -rc4 -nosalt -pass pass:"$(dd if=/dev/urandom bs=1k count=1 2>/dev/null|base64)" </dev/zero
