Of course, one is slightly skeptical when you do read some not so great reviews here. But I can reassure any. This little (and slight) external hard drive with a huge carrying capacity does exactly what it should: store data. Because of their size it is certainly meant to supplement for laptop PC. I use them as hard drive for recording TV programs to an active USB port on your TV. Recognized and records perfectly. So she comes out with no additional power supply and I think that before super. In 2 meters it is almost inaudible, quieter than any VCR.
Half a point could be pulling because the USB cable is quite short. I do not mind that laptop users certainly not. If the cable is too short, one buys a corresponding Longer.
Price / performance relate to each other a good relationship. Long-term experience, I can not offer course.
