Sequential Write in FOB
From diagrams below, we can find P41 has much larger SLC cache. It may be the reaon P41 enters PS4 later and get a much higher PS4 power in the earlier test results.
990Pro’s temperature is still very high.
Gen4-Gen1 seq read performance
Gen4 read write performance
P41 and 990Pro have excellent performance, but others are also good enough.
