Good but very fragile
For the price, the quality is more than adequate. Very high speed compared to other external hard drives, and equally high storage capacities. So why this rating? Fragility. All it took was a slight knock on my rear door during a journey to render it unusable, with total loss of data (data unrecoverable even with the right tools). Suitable for use that does not require moving or for those who are dexterous with their fingers. Otherwise, all it takes is a slight shock to render it completely unusable. I remember having an external DD that fell heavily 3-4 years ago and never had a problem. This one had a little boo-boo and it's already the end of the beans.
