"Data transfer rate (as of 2008) at the inner zone ranges from 45 MB/s to 3.0 GB/s, while the transfer rate at the outer zone ranges from 74.0 MB/s to 111.4 MB/s.^{[citation needed]} In contrast, the first PC drives could manage only around 40 KB/s."

All I can say is that there is at least 1 wrong "fact" there - any given mechanical disk with a fixed rotational speed will always exhibit a faster transfer rate at the outer edge than at the inner edge.

Those are the sort of "benches" I am thinking of yes - as justaviking already posted for one of the very latest and greatest SSD drives from Intel (already superseded by something better btw). My request for a bench was more to substantiate that 3GB/s claim that imo is obviously bogus in that article
