In 2003 Seagate, Maxtor, Fujitsu, and Hitachi GST released a joint
"position letter" announcing that we'd start to see disks with
4-kilobyte[0] sectors "soon".  The original estimate was that such
drives would ship in 2006, but I'm reasonably certain all the 750GB
disks that I've seen have 512-byte sectors.

4K, BTW, is conveniently the size of an i386 memory page.  Fair enough,
I guess; IIRC, the 512-byte standard came from the VAX memory pagesize.


[0] Real kilobytes, not this "but it's an SI unit" whining or
     kibibibibilitibytes nonsense.
