Cost of storage vs DVD: BD=16x, CD=6½x, HD & DVD-DL=5x

Just a quick followup note from a thread I did on Twitter yesterday on the prices of a Gigabyte of storage on various media.

DVD’s are still the king at just over 3¢ per gig:

Kind ¢/Gig xDVD
Blu-ray DL 25.0¢ 7.8x
CD 20.5¢ 6½x
DVD DL 11.0¢ 3½x
Blu-ray 10.4¢ 3¼x
Hard disk 8.9¢ 2.8x
DVD±R 3.2¢ 1x

I find the dual-layer DVD vs hard drive equivalence fascinating, especially after talking with Iain yesterday about
the eSATA ports on my Mac Pro’s motherboard.

and Fortune Computers.
