I bought the part, I'm happy with it, but it's not very stable, which means if it fell down I'd have 100 parts and it would be broken, very thin plastic, not hard plastic, like a cheap toy car...But one more question, what does it look like inside? It's very quiet and when you put your hand on it, no movement inside, even though it's running or reading or writing.When I hold my hand on the WD hard drive, it rumbles a lot, but nothing here.New hardware inside for hard drives ?
