Summary: A great HHD, well made and function as designed. I used this drive with a USB-3 external enclosure because I wanted the higher speed possible with the combination. I love it and would recommend this to anyone. While I didn't use it in my laptop, it would certainly fit and function well in it.
Summary: I bought 17 units. They sent me a wrong part number: ST9500420AS instead of ST9500423AS. The ST9500420AS is an old model with diferente specifications. I was charged with US$ 5.95 for the shpping for every hard disk and I expected for a great package. I received the 17 units in a box almost without wrappers!
