The 12TB is $199 right now on Amazon.
Running memory tests as we speak. I'm starting to think it may be the SMR drives too. I bought 3 of these today and plan to shuck them and set them up in a mirror configuration with one as a backup. People are saying that they are CMR drives.
We are talking about this one's: "https://www.amazon.com/Elements-Desktop-Hard-Drive-WDBWLG0080HBK-NESN/dp/B07X4V2M3B/ref=mp_s_a_1_3?dchild=1&keywords=wd%2Belements&qid=1602581832&sr=8-3&th=1&psc=1"?
