I posted earlier about buying an internal hard drive for my mac pro and G5. I have been doing research on the Net and gone to sites that have done Benchmarks on the different drives. I have narrowed it down to the one I want to buy. Here is my question. 1. What is OEM? Can these Drives be trusted? Are they made by some third party in China and slapped a label on them from the manufacture? Are the internal parts the same as the Manufactures that sell them? Where do they come from? How do people that sell OEM Drives on Ebay get them from? Am I taking a huge risk buying an OEM drive? There is such a huge price break between OEM and Retail, have you had experience in this area?
