efficient approach.

Each additional disc is a capital cost.  Running each extra disc takes extra power. (Accepted negligible if they spin down)  Each 
disc needs more case space and system resources, if available, such as a spare interface and extra heat removal capacity...  If the 
recordings are smaller each HDD will go further....I'm not really sure there's any rocket science in this...

>Disks spin down when not in use.

My backend currently has a small (120G) disk for the OS and 2x2T discs.  A bit of reading up on this (thank you (again!) for the 
prompt) tells me spinning down is not set by default, but its ready to be set in myhthbuntu in /etc/hdparm.conf, I might see if I 
can get the 2T drives to spin down. (cool!)

Agreed, however that does not change the proposition.

OK.  Sounds like you'll be staying on DVB-S for some time to come then!  (Maybe Satellites are more quake proof too?)
