said by Morris0: Actually, one of the drive is *already* a WD.
Have you tried a WD or Samsung drive?
If you carefully read the Dell kb and al the posts here ( yeah, right ) and you meant: "Have you tried two WDs or two Samsung drives?" the answer is "No", but I already drew up some plans in my previous post.
However, from a practical point of view, such configuration would be nearly useless for me, so I may or may not try it. Removing/swapping drives in that SFF case is rather cumbersome.
