I am making no such assumptions about the quality of either SSD...you are. You are saying Apple's SSDs are of better quality. That may or may not be the case but you have yet to provide anything to support your assumption.Again, quit making the assumption that it is the same quality ssds as those. Performance speaks for itself compared to a lot of other laptops out there.
Meanwhile I've pointed you to a "competitor" which offers the same performance with a longer warranty and at a lower cost. Regardless of the quality that "competitor" may be it offers everything the Apple SSD does at a lower cost.
