The last time I looked at those (which was a few years ago) they were competitive
with tape for power consumption, but not on cost per terabyte - it takes a lot less
cable and hardware to hook up a dozen tape drives and a robot arm that can
reach 10,000 volumes than it does to wire up 10,000 disks of which only 500 are
actually spinning at any given time...
