Archival cost of hard drives

At the prospect of being able to archive HD content for future viewing, 
I was curious what the "cost per movie" would be to just buy extra hard 
drives and swap them out vs. archiving to DVHS tapes.

You can regularly purchase a 250Gb drive at Fry's for $99->$139 
depending on the current sale/rebate.

A 2 hour movie at broadcast bitrates would be about 14Gb.
At satellite broadcast bitrates, it would be about 8-10Gb.

A 250Gb drive should hold about 16-28 movies, putting the cost at 
$4->$9 per movie (depending on bitrate and drive size).  That puts it 
in the same range as DVHS tapes.  Not a bad proposition.  Of course you 
need an enclosure (Firewire/USB2.0) that you can easily swap the drives 
in and out of or you have to add the price of an enclosure to each 
drive.

Just thought that was interesting.
