Crucial P310 2280 4TB vs Seagate FireCuda 530 4TB
Seagate FireCuda 530 4TB 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 P310 2280 4TB states 7100 MB/s read and 6000 MB/s write; Seagate FireCuda 530 4TB states 7250 MB/s read and 6900 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.
Random access
Crucial P310 2280 4TB is rated 1.000.000 IOPS random read and 1.000.000 random write; Seagate FireCuda 530 4TB, 1.000.000 and 1.000.000. Random 4K access — many small, scattered operations — is what a drive does booting, launching apps and juggling everyday tasks, and it tracks that feel far more closely than the sequential figures above.
Price
Crucial P310 2280 4TB is 565,21 € (141,30 € per TB); Seagate FireCuda 530 4TB is 530,02 € (132,51 € per TB).
Endurance
Crucial P310 2280 4TB is rated for 800 TBW and Seagate FireCuda 530 4TB for 5100 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: the catalog does not state whether Crucial P310 2280 4TB carries a DRAM cache, and Seagate FireCuda 530 4TB carries a DRAM cache. 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 P310 2280 4TB's NAND is not stated, and Seagate FireCuda 530 4TB 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 P310 2280 4TB's controller is not stated and Seagate FireCuda 530 4TB uses the Phison E18. 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 P310 2280 4TB carries a 5-year warranty and Seagate FireCuda 530 4TB 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, Seagate FireCuda 530 4TB is even or ahead on every tracked measure and behind on none, which is the one case where the choice needs no compromise.
