Why would you spec a hybrid drive as your secondary drive?
Seagate has a few bad models, they are not all bad. In fact, I have one of the ill-fated 3TB Barracudas... and it has been fine up to now (but I wouldn't go out and buy another, mind you, based on the absurd failure rate.) But I have 8 other Seagate drives (500GB, 1TB, 2TB) in service and they have all been 100%, and I would buy another non-3TB Seagate tomorrow if the price was right.
Seagate is the current whipping boy of internet rangers, just like the Samsung SSDs are, at the moment... everyone seems to forget the other manufacturer's bad drives (early Hitachi Deskstars, for example.) I had a brand new WD Red come out of the box with bad sectors... so it happens to everyone.
