It's very time consuming so it has to be something really worth keeping. It would be great to do this from inside myth even if it was "only" AVCHD disks (I know, patches welcome...) but for now I use Toast on my Mac.

Burning to bluray only makes sense if you specifically want to use them 
on a standalone player.  You're looking at 0.15£/GB for bluray, versus 
0.035£/GB for hard drives.  One could argue that a bluray may be more 
reliable in the long term than a hard drive, but for 4x the cost, you 
could afford to cycle multiple hard drives to ensure a single failure 
won't be a problem.  That's not even taking into account the fact that 
you have to swap out 80 BD-Rs manually for the same storage of a single 
2TB hard drive.
