Samsung is going to introduce a 4TB Pro model SSD during CES on the 850 range. We've already seen the EVO model being released at that capacity, however a new PRO model will be added to the line-up as well.

The main difference in-between the EVO and PRO models is that the first one is TLC (three bits per cell) written, and the Pro model as MLC (two bits per cel) That effects both performance and endurance. The announcement will be made at CES, it is currently unknown what controller the SSD is going to use.
