I don't suppose anyone knows if the platters are read in parallel?
A nice idea, but I wonder if it would help? You'd need a lot of cache
memory for one complete revolution x no. of surfaces, and the data
transfer rate of the HD interface might be the limiting factor anyway.
Modern disks are zoned, so there are more sectors per
track near the edge
Yes, that's the whole point of this discussion.
See http://www.storagereview.com/guide2000/ref/hdd/geom/tracksZBR.html
for a table showing a typical drive. The transfer rates vary from 372
Mb/s in zone 0 to 173.8 in zone 14.
