For both my gaming machine and my Macbook Pro 2011 i7. Ouch! But I am sure it will be well worth the cost. Is there anything I need to look out for or do before installing this model? I didn't want to have a unreliable OCZ product so I went this route. I over nighted them to my work so I get it by tomorrow. I had a 128gb Vertex 2 OCZ in my gaming rig and it died last night. My boss had the same one in his and it died 3 months ago. OCZ customer service stinks and takes forever to replace anything. So I am going to get a RMA replacement and sell that good one to help recover the costs. And per the OCZ forums many are saying stay away from OCZ due to so many failures!
