I am running ADSM version 3.1.0.2 with all version 3 clients. The tape storage
hardware is DLT7000 drives with the latest STK firmware 7.0. The tape media is
Fuji DLT_IV cartridges.

I am concerned that I am not getting the compression DLT 7000 media should
give. I am not running any client compression, hoping to really verify how good
or bad the hardware will compress. Does anyone have any ideas on how to
accurately measure this or has anyone experienced this same scene.
