I quote from the PMR:
"The over head should affect sequential access volumes in general,
however there are other factors that can come in to play on a physical
tape devices that would not affect a file devclass. These other
factor can include volume capacity, hardware compression and the
block or header sizes dictated by the actual device. Because of
these conditions, the waste seen on a FILE volume may not have the
same impact or even noticeable on tape volumes."
So your mileage may vary, I guess...
