Omg Hitachi...
Every single Hitachi HDD I ever had died.The hell with them lol!
Seagate is the best!
I prefer Seagate, Western Digital or Samsung hard disk drives. But it also depends on the model. Every manufacturer releases some defective models of drives. Right now I would stay with 1.5 terabyte and smaller capacity drives. They tend to be more reliable than larger capacity.
I stay away from Hitachi hard disk drives.
