Can you explain exactly what this means?

Hmm.  Isn't that more a reflection of the inefficiency of the software?
Given that the SCSI-2 interface on my Performa 475 can shove data into
the 1GB ext HDD at 3.8MB/s (measured sustained data rate), you could
expect efficient software to write once over the entire disc in
something of the order of 5 minutes.
