Access, or read speed?

I can quite believe DVD-like access times, but given the data density, I'd expect read/write speeds to be much, much higher.

Had a quick shufty on the Storex site and couldn't see any hard figures - so presumably they are talking theoretically - that is, they have made this on a 10mm^2 sheet, and have scaled it up to the size of CD shaped disc.
