Ah Ha!! New acronym. Should've guessed it.

I'm looking at an array of less expensive drives like the Ecrix gen 2
drive (still $1k but now does 12MB/sec). this won't come close to
saturating the U160 controller so hand 2 drives. The Ecrix drives can
also do variable speed writes by slowing the tape down if the need
arises.
