Summary: After having this drive (1TB 12.5mm 2.5" notebook drive) in my 13" 2010 Macbook Pro Unibody for about 3 months, it crashed on me. Unfortunately I had not done a backup for about 2 months, so I lost a fair amount of data.
Summary: I purchased this to max out my mid 2009 MacBook Pro. I was hesitant to tinker as I have had no problems in 2 years. For the first week it worked great. the I started getting slow downs and system hang ups. I used tech tools deluxe and found hundreds of bad sectors.
Summary: I ordered one to install in my MacBook Pro and it worked rather slowly for two weeks until it eventually failed with white screen of death. I then reinstall from scratch (I had imaged it with Clonezilla at first) doing all update and recovering with time machine.
