Google returns nothing on native 4KB drives at any drive vendor site,
other than two transition documents at Seagate and Toshiba extolling the
benefits of 512e technology.

I can't find a press release.  If native 4KB drives are indeed
available, the vendors sure don't appear too eager to tell the world
about them.  The drives of which you speak, are these engineering
samples, OEM production only (EMC/IBM/etc), or general availability?

Which vendor makes the drives of which you speak?
