The first ones that haven't developed any pending/remapped sectors during the 9 months they have been in 24/7 use. Previously tried different Seagates, with constant problems (And yes - Had the SCT turned on). Also tested a WD r= ed, but saw similar symptoms developing and so degraded that to a storage disk for my boy... HGST was some 20=E2=82=AC more expensive and hard to get here but defin= itely worth it.
