Crucial P3 Plus 2TB vs Kioxia Exceria Plus G3 2TB
Crucial P3 Plus 2TB is at least the equal of the other on every measure that decides this, and ahead on at least one.

How these two compare
Sequential throughput
Crucial P3 Plus 2TB states 5000 MB/s read and 4200 MB/s write; Kioxia Exceria Plus G3 2TB states 5000 MB/s read and 3900 MB/s write, both over PCIe. Sequential numbers like these describe large sustained transfers; the responsiveness you notice day to day tracks random access more closely than the peak figures do.
Price
Crucial P3 Plus 2TB is $396.00 ($198.00 per TB); Kioxia Exceria Plus G3 2TB is $572.00 ($286.00 per TB).
Endurance
Crucial P3 Plus 2TB is rated for 440 TBW and Kioxia Exceria Plus G3 2TB for 1200 TBW — the total the maker warrants you can write over the drive's life. A typical desktop writes only a few terabytes a year, so either rating is many years of headroom; the figure matters mainly as a relative signal of how hard each is built to be driven.
DRAM cache
On the cache question: Crucial P3 Plus 2TB is DRAM-less, and Kioxia Exceria Plus G3 2TB is DRAM-less. The DRAM keeps the flash-translation table close, sparing a lookup on nearly every access; a drive without it leans on host memory or its own flash, which usually shows as slower sustained random writes rather than in the headline sequential numbers.
NAND, controller and warranty
On the flash itself: Crucial P3 Plus 2TB uses QLC, and Kioxia Exceria Plus G3 2TB uses TLC. NAND tiers count bits per cell — more bits pack more capacity into the same silicon but shorten write endurance and slow sustained writes, which is why QLC sits below TLC on lasting performance even when the sequential numbers match. Controller: Crucial P3 Plus 2TB uses the Phison E21T and Kioxia Exceria Plus G3 2TB uses the Phison PS5021-E21T. The controller runs wear-levelling, error correction and the mapping table, so it shapes sustained and random behaviour as much as the flash does — though the model name alone predicts little without testing. Crucial P3 Plus 2TB carries a 5-year warranty and Kioxia Exceria Plus G3 2TB carries a 5-year warranty — the length the maker will stand behind the drive, and usually a proxy for the endurance it is rated to.
Which to buy
Against the other, Crucial P3 Plus 2TB is even or ahead on every tracked measure and behind on none, which is the one case where the choice needs no compromise.
