RE: Blockbusting news, this is important (Re: Why are bad disk sectors numbered strangely, and what happens to them?)

[David Lang]

rotating storage is hitting $1 per gig, memory is running ~$100/gig
(substantially more for the highest density memory)

making a small solid state drive is easy, cheap and definantly has some
uses, but making something that will replace stacks of 300G drives is
neither cheap or easy.
