I have 970 Pro and in most real world scenarios nothing beats its MLC FLASH.
980 Pro is faster cause of interface in sequential but slower in other tasks. Should I mention double endurance?
More layers will mean higher capacities what is good but how about prices? QLC is cheaper and crappier then TLC. Already QLC drives in consumer segment have only 200 TBW. On huge drives this might seem good but is it?

So the current Samsung SSD 980 PRO PCIe 4.0 delivers 7,000 MB/s read speed and 5,100 MB/s write speed. How fast do people think the upcoming 990 PCIe 4.0 will be? FYI the Sabrent Rocket 4 Plus PCIe 4.0 2TB SSD does 7,100 MB/s read and 6,600 MB/s write, and the upcoming 4TB model could be even faster.

Those are the speeds they market to everyone. What we really need is an improvement in random IO as its mostly flat for years. In fact none of the PCIe 4.0 drives improved random IO some actually are worse.
