Common questions
Is the 4TB 990 Pro any slower than the 2TB?
Samsung's page rates the 4TB at 7,450 MB/s reads and 6,900 MB/s writes, the same headline figures as the 2TB model.
Should I buy the heatsink version?
Samsung sells a separate heatsink model. Most desktop motherboards include an M.2 cooler, so it mainly matters for PS5 consoles or boards without one.
