Cheap drive doesn't a unreliable drive make.
And as the text said - all of the drives are "consumer" grade drives, which offer the best capacity/price -ratio, so grouping by manufacturer is fair.
When buying a new drive, I - as one - will go to the one with the cheapest capacity/price -ratio (if not special usage - portable or SSD speed needed)
The most puzzling thing to me is what is said about the WD Green 3TB and Seagate LP 2TB drives. "...two specific drives that would not work well in their particular hardware configuration"
What kind of hardware configuration you will need that it destroys drives? At first I thought that in such a data storage company those "Green/Low power" drives would spin up and down repeatedly so they would fail immaturely. But wouldn't the drives spin up and down at a elevated pace even at home usage? So those two drives would be not recommended (except for certain uses).
