This post was prompted by questions on 3TB drives and the WD Black drives. Ditto on Black being overkill and running hotter, which you want to avoid in AV application...
Update on my WD 3TB AV-GP (WD30EURS) installed in a Rosewill RX-358 U3C v2 enclosure connected to my HR-34. l am happy to report it has been working flawlessly for past 6 weeks. See my previous posts regarding some initial issues, that have remained resolved.
After my reading this thread and my limited experience, I would recommend sticking with the AV-GP series. Here is a link to the WD website that categorizes their drives by intended application: http://m.wdc.com/en/...nternal-storage
I figure if WD markets a drive to be used in a particular application, they are not trying to "upsell''. I assume their intention is to make it easier for the customer to get the right hardware. The correct drive for a particular application will probably result in the best performance. Good performance = satisfied customer = repeat purchases.
