Wdc, tler, $$$$

So my understanding from reading a few message boards is that any WDC drive given the proper firmware could be used in a RAID environment, but WDC has disabled this ability in their newer firmware for many drives.  Is that true?  And if so, why?

Maybe you should try contacting WD’s Technical Support about this. You can do so either by phone or email. They will let you know exactly the reason why.
