I assume you mean for the standard tape drive, numbered 6157-002.

I've been using -C2000 (2000*512 byte = 1Meg size clusters) and the
prformance in quite good.  I've never fiddled with the density, as
700 (or is it 500) is the default, and I'm sure it was chosen for
a good reason :-).  The -C<#> default is 1 (if memory serves me).

The time to fill a 125-150Meg tape is about 25-35 minutes with the
-C2000 parameter.

May you never have to use any of the backups you make.
