This is the original 512gb model.  I upgraded it and put a brand new 2280 2tb nv7400 ssd.  The ssd alone cost over $300.  It has max read speed 7450 mb/s and write speeds 6500 mb/s.  It has not been played on more than 30 minutes and most of the time being on i was setting up my emulation.  I ended getting something different and have no need for it.  It comes with all original packaging and will be factory reset.
