Corsair MP600 CORE XT 1TB vs Western Digital WD_BLACK SN770 1TB
At least one of these has no price the site currently tracks, so what follows weighs specifications alone.

How these two compare
Sequential throughput
Corsair MP600 CORE XT 1TB states 5900 MB/s read and 5000 MB/s write; Western Digital WD_BLACK SN770 1TB states 5150 MB/s read and 4900 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.
DRAM cache
On the cache question: Corsair MP600 CORE XT 1TB is DRAM-less, and Western Digital WD_BLACK SN770 1TB 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: Corsair MP600 CORE XT 1TB uses QLC, and Western Digital WD_BLACK SN770 1TB 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 MP600 CORE XT 1TB uses the Phison PS5021-E21 and Western Digital WD_BLACK SN770 1TB's controller is not stated. 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 MP600 CORE XT 1TB carries a 5-year warranty and Western Digital WD_BLACK SN770 1TB does not state one — the length the maker will stand behind the drive, and usually a proxy for the endurance it is rated to.
Which to buy
The site holds no current price for at least one of these, so it cannot call the buy on cost. Judge them on the specifications above — at the same capacity and interface, two drives usually part on things like the DRAM cache, the NAND tier, endurance and warranty, so weigh whichever of those the sections above report.
