James Hughes talked about these at MSST last year, and some of his colleagues demonstrated the hardware: <http://storageconference.us/2014/Presentations/Hughes.pdf> For tinkering purposes there is java based simulator: <https://developers.seagate.com/display/KV/Kinetic+Open+Storage+Documentation+Wiki> The drives do use a key/value interface. --phil > On 9 Apr 2015, at 17:01, Mark Nelson <mnelson@xxxxxxxxxx> wrote: > > Notice that this is under their emerging technologies section.
