This hard drive is running for around three weeks quietly and quickly. I've checked with a test program, because the packaging quality was outrageously primitive. As insulation lay down 2 advertising list, as insulation up was slightly crumpled wrapping paper. As insulation to the edge said paper was as Knüllung. This is a stupidity the packer without equal. Otherwise, the board was pretty big, but the plate had been found to be defective and that was the important thing. It runs very quiet, has its speed and is still in order. If compared to a WD1TB Caviar Green as quiet and energy efficient. No more nagging from me! Would buy this record again, but with a better package. The date was also observed. The package was delivered super fast.
