The Crucial P5 Plus is not one of the faster SSDs, that crown belongs to these SSDs: WD Black SN850X, Samsung 990, FireCuda 530, Kingston Fury Renegade (and the practically equally fast KC3000) and one that doesn't have NVRAM but is also very good, that would be the WD Black SN770, which also manages 5150 MB/s and 4900 MB/s, a very good performance for one without DRAM cache and in the PC Mark 10 Quick Benchmark it was even the best.
The Samsung 980 Pro is far behind, if Samsung, then the 990, but certainly not the 980 Pro. Those days are definitely over. These are the current best (whereby the FireCuda 530 takes the cake in terms of durability, it can write approx. 2500 TB, while others can do just under half that), I would buy one of these :).
