BD is 5.3x higher capacity than DVD. Thus, BD’s price has to be 5.3x higher than DVDs to equal the value.
So 0.20c x 5.3 = $1.06. I have not seen BDs selling for that price; so DVDs are still better value.
Including cost of the drive, as all PCs come with DVD burners for free.
Plus, I wouldnt risk placing 25gb of stuff on plastic. I as well dont use higher than 4gb cards, and still
use CD-Rs as 2nd backup to DVDs. I bought 2 500gb hdds instead of 1TB for fear of failure. Cost
comes out to $120 either way. One is at home, other in the safe box at the bank.
