With the 20Tb/60Tb capacity, the only thing that would come close to "fully utilizing" such a tape would be some massive single-thread backups (remember, only 1 application can write to a tape at any given time) or be used as a backstore in a VTS solution. For that, they are perfect (IMHO). You can run 4, 8, 16, 64, or even 128 concurrent backups to a VTS solution so you are done with backups much quicker. Then, as a background task copy all those virtual-tape-volumes to a high-capacity physical tape(s) with a 20Tb or 60Tb capacity. Best of both worlds. Fast concurrent backups and physical tape for high reliability and portability. Most sites prefer to use replication, but I like a copy on physical tape. But, I have a huge affinity for physical tape (actually, tape in any form suits me).
I remember the neat system that STK had for a while (still might) where you can run 3 or 4 DFDSS backups to a single tape volume (the tape volume was allocated to a different sub-task that the 4 DFDSS backups were communicating with). It was neat that you could run 4 DFDSS backups concurrently and since the tape was so fast it could keep up with 4 DFDSS systems writing to it concurrently. But the benefits of a VTS solution doomed that as well.

That's all we have now.
