Hitachi HDS723020BLA642 2TB 64MB Cache

Hi guys. Well, I finally finished my four 2 Terabyte drive expansion. The good news is that these drives worked fine with the 4.1.7 firmware. I put up all the pictures. So after adding the last drive, the nas didn't automatically expanded. I had to reboot, then it started and once it finished I got a total of 5560GB of space two and a half days later. You will need to reboot like two or three times before everything gets done. Also, Hitachi did get back to me with this link, I do like that they always show you a lot of the technical information if you need it, so you can check your drives here:

I hope this is helpful to anyone else using these drives. They cost much less than the 3 Terabyte drives so hopefully I'll have plenty of space until I can get something bigger. In the meantime, has anyone used (tested) the 3 T drives in their NV+? I'm just curious? I should also note that I prefer to use retail package drives. I know some people have other opinions about this, but hey I have my reasons and they have worked fine every time and many times I do get them for less than what some bare drives are selling for. I don't need dead drives on arrivals, but again, this is just my own personal opinion so take that as you like, there no need to flame me or start a conversation about what's better. Just get what you like and this is probably why I waited this long too. :)
