A holding disk still buys you parallelism.  Sure, a local full
backup can provide bytes faster than a typical tape drive can
consume them.  But on an incremental, dump or (especially) gtar
can spend a lot of time searching for the next file to back up.
During that time, bytes aren't being copied; in a direct-to-tape
dump, your tape drive sits idle; with a holding disk, the drive
could have been writing a different DLE.

It must be said that they would have sounded better if the singer
wouldn't throw his fellow band members to the ground and toss the
drum kit around during songs.
