How can I find one of the newest drives?

I want a passport drive that has the newest VCD, one that loads only if you have encryption turned on, how do I find out what drive to get?? What model number? What revision?

The ones Costco is selling for $99 appear to all be the new kind. I got two like that a few weeks ago. If you can, just get one there.  It would be nice if WD could answer your question, though (Hello . . . Anybody Home ???). Seems like a pretty basic thing; same question I asked at the end of the orignal post here.
