Where are the new 1-8 bay Red drives with Nasware 3.0 firmware

I am looking to update my 6 bay Qnap NAS with new 3 or 4 TB drives, but amazon, wd, and new egg do not have the new version of this drive yet!. 

Any ideas when I can by the newest drive.  It would seem the new drive reliability would improve when comared to the 2.0 version.

Hello,

Have you tried contacting the WD Online Store?
