Yeah! As if people look at the tech spec PDF at the very bottom of the page if there is not any indication on the main page that some features might differ from drive to drive - so no in that situation people do not look at the PDFs. The main product page clearly states OPAL 2.0, and honestly I think that is very misleading - and not only to me if u check out the online stores listing the X400 drives. Example here a European search Engine:http://geizhals.de/sandisk-x400-512gb-sd8sn8u-512g-1122-a1368870.htmlIt states 256bit encryption and many store sites linked there do have those specs up to sell the drives. i.e.:http://www.future-x.de/sandisk-x400-solid-state-disk-verschl%FCsselt-p-287266/?pv=2So if what you say is true Sandisk has to some major correction to distributors and resellers.
