Use them in multiple drives, and their longivity and reliability seems to fall off the charts. I wouldn't miss them if they were to fall off the earth tomorrow. (Aside from all the data I have one them, of course.) DDS-3 is better, but I don't have enough long term experience with it to know how much. Even on the machines I have with DDS-3 drives, I still have to use them in DDS-1 mode, because we have to read the tape on any of our machines.
