A number of older systems (zseries ztpf/nonstop/others) are used like this (basically a log dump on an interval).
LTO is designed to speed match to avoid shoe-shining (rewind/rewrite). AKA the drive changes the speed the tape is moving past the heads to accommodate the read/write speed of the application. Which is one of those fun computer cases where you can literally hear how fast your application is running. The more recent drives have very large ram buffers to smooth it all out too.

If these are representative, then you get about a factor of 3 to vary the speed, and the minimum is still way too fast to record most live drive use.
