I'm planning on buying the unibody 17" MBP. I want to get a 256GB SSD with it, but I am unsure of the quality of the SSD that can comes with the MBP. It is a $750 upgrade and 3rd party 256GB SSD drives tend to be slightly less expensive. The price is not really a factor. What I really want to know is how does the performance of the standard Apple 256GB SSD compare to the performance of a 3rd party SSD? Should I get the SSD included with the MBP or buy one separately? And if I should buy one separately, which model SSD should I get? Thanks.
