'It Depends' of course.

Got Ultrium 4 or 5 tape? That's certainly going to be fastest almost no matter what.

If you have a system with very few drives, tape is likely to win as well.

If you have a bunch of drives or you have the Virtual DVD in a separate ASP then it could be faster than most mid-speed and slower tape drives (i.e. LTO2 and slower) but not by a lot over LTO2.

Compared to Physical DVD-RAM though, there are NO options that are slower than that. :-)

Does a save to virtual DVD run any faster than a SAVSYS to tape? Or is the speed of SAVSYS more a function of the data retrieval and formatting rather than media/I-O speed??

Absolutely. Works fine.

Do be aware that for it to be useful it must be sized to fit a real DVD
disk, *OR* you can put it into an image catalog and use it for an
upgrade. Also with POWER6 and newer you can use them with network based
virtual optical to do upgrades to other partitions.
