How these two compare

Sequential throughput

Corsair MP700 Pro SE 4TB states 14000 MB/s read and 12000 MB/s write; Crucial T705 4TB states 14100 MB/s read and 12600 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

Corsair MP700 Pro SE 4TB is £484.88 (£121.22 per TB); Crucial T705 4TB is £494.99 (£123.75 per TB).

Endurance

Corsair MP700 Pro SE 4TB is rated for 3000 TBW and Crucial T705 4TB for 4800 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: Corsair MP700 Pro SE 4TB carries a DRAM cache, and Crucial T705 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: Corsair MP700 Pro SE 4TB uses TLC, and Crucial T705 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: Corsair MP700 Pro SE 4TB's controller is not stated and Crucial T705 4TB uses the Phison PS5026-E26. 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. Corsair MP700 Pro SE 4TB carries a 5-year warranty and Crucial T705 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.
