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. It was still slow and failed again with white screen of death. I reinstall my old drive and everything works fine.
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. I tried to look up support and discovered that Samsung doesn't even recognize the model number as a legitimate product on their site.
Summary: I gave this 2 stars for fit and runs silent. Ordered two,installed one in my 15" Macbook Pro, after three weeks of used the drive failed. Try disc repair and tried to reinstalling operating system but keeps failing with errors. I have now installed the second one and returned the first to the manufacture for replacement. Let see how long the second one last....
Summary: Bare Drive - No kidding. That's pretty much all that was in the box. Not even a receipt, which would have been nice (hence only 4 stars). Pretty fast delivery. Other than that, it works. I installed it in a Patriot Box Office Media Player so now I don't have to deal with streaming my videos and music from my main computer over my home network.
