Iomega has sold products - though none
currently - that save cost by sharing the
same electronics among multiple removable
Whenever you talk to a new LUN, the heads of
the last LUN park and the heads of the new
LUN move out on to the media.

Iomega's current products are bumping up
against the 4GB and 10MB/s limits - shipping
1GB and 6MB/s at $99 a cartridge.
I know we hate using up a whole 32 cluster
cluster to store one byte just because some
idiot somewhere in the system only has 16
bits to count clusters.
I know the RAID people like to hook up a set
of disks and make them look like one. That
makes 7GB easy - what are they doing?
On the drive firmware end, we've talked
about aliasing media: let LUN 0 see the
whole capacity, let the other LUN's just see
a piece. Dunno if that would really work
for the host folk or not.
