After 2 years of usage, my 500GB WD Green started to act strange. The drive is almost filled up. read/write speed is still good at about 80-90mb/s. But when i'm playing games, it freezes and lags horribly (League Of Legends freeze everytime something demanding is happening, or i randomly click somewhere on the map. TF2 and CSGO freezes when i changes the graphics settings). This is not a graphics card related problem, because in any other games like Shadow Of Mordor or Darksiders 2 everything works smoothly. All the smart attributes are still in good condition. Is there a problem with my drive???
