Verified Purchase(What is this?)
This review is from: Samsung 840 Series 250GB 2.5 inch SATA Solid State Drive (Accessory)
Bought this for a mid 2011 MacBook Pro 13", I used super duper to clone the existing hdd to a USB external drive. Watched a video on YouTube and then replaced the existing hdd with this ssd. Easy to install, super fast response times. I had recently installed mountain lion, an this ssd makes up for he drop in response times and more.
