I've seen people ask about them so I thought I'd run a few little benchmarks to give you an idea on speeds. I am aware people have problems with spending so much on a 512GB SSD, especially from Apple. But for some people it's no problem, not to mention it was actually cheaper to get the Apple SSD by $200. (Where I live at least). I wasn't opening a debate on the hardware. Simply posting the result which may/may not help people.
