Summary: I ordered this by mistake. It is NOT intended for a laptop, as it is too thick. It's rated for enterprise use, so I imagine it's for servers that need to be physically small. I've never had a problem with a seagate HDD, and I've seen hundreds, so 5 stars. Didn't know they made 2.5" drives this thick. Again: DO NOT BUY THIS FOR A LAPTOP, IT IS PHYSICALLY TOO LARGE.
Summary: Just receive it, great shipping and handling, I'm gonna used it next week for replacing an old drive that fails from a DELLs EqualLogic. Hope it works, it's the same model brand etc etc, but a different firmware. If it is use in Dells EqualLogic units for professional use, it seems to me that this drive should be good and reliable for heavy duty and sensitive data storage.
