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 re-installed Win7 Pro from a previous bad hard drive. It worked like new and was very fast; a cold boot took about 30 seconds. How long this will last, I'll never know. I repaired a broken laptop with this and immediately sold it to a well-pleased buyer.
