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. -- Anahata anahata@xxxxxxxxxxxxxx -+- http://www.treewind.co.uk Home: 01638 720444 Mob: 07976 263827
