I didn't downvote, but /dev/urandom isn't a particularly large bottleneck for any recent machine. I've got a 4 generation old I5 (3570) dd of /dev/urandom gets 300MB/sec for me. SATA is only capable of twice that, so it's not a particularly large bottleneck.

I do wonder what machine you used that's 20 times slower than a 4 generation old i5.
