> Yes, the cost progression of storage is expressed by Kryder's law, and is actually faster than moore's law. (well, in terms of storage space, not storage speed.)

In theory, not necessarily in practice. The Thai floods caused a multi-year pause in Kryder's law we're still recovering from. (I'm not sure how robust Kryder's law is - there's a lot less data and analysis of it than Moore's, since that's the famous one.)
