If you read my post, you will see what I suggested. Price differences for higher/lower quality components. They do it with CPU's. For example an Intel model X 1ghz vs 1.1ghz chip is exactly the same chip, only one came out better quality in tests and so is clocked at the higher rate. I pay more money for a faster CPU that is in fact exactly the same chip as the cheaper one! Why can I not pay more for the faster SSD that is built by a completely different company? Supply and demand can solve the problem of "What does Apple do if they can't source enough of the same SSD's".
To be honest I don't care what my Air will have. Random read/writes is more important to me and SSD benchmarking is complex. But if components are going to have significantly different performances, there should be a choice made at purchase time for higher costs for less supply. I'm not saying they are doing anything illegal at all, but I personally would be happier if it was done that way.
Each to their own.
