The write cache is fairly large, if you keep the drive relatively empty it will perform better. How full is it?
The good news is, the P3 Plus can absorb up to about 550GB of writes within its pSLC cache. This indicates that all of the QLC is capable of acting in single-bit mode for a total cache capacity that’s one-fourth of the flash. This cache will diminish in size proportionately as the drive is filled based on how much space is left free. A large, dynamic cache is a good way to hide weak native performance. The P3 Plus’s cache is ample to handle typical, bursty workloads.
