How these two compare
Sequential throughput
Kingston NV2 1TB is rated 3500 MB/s read and 2100 MB/s write; Western Digital WD_BLACK SN750 SE 1TB, 3600 MB/s read and 2900 MB/s write. These are peak sequential rates over PCIe — the speed you would see copying one large file. For boot, app launches and everyday feel, random access matters more than this headline figure.
Price
Kingston NV2 1TB lists at $179.00, or $179.00 per TB; Western Digital WD_BLACK SN750 SE 1TB at $163.75, or $163.75 per TB.
DRAM cache
Kingston NV2 1TB is DRAM-less; Western Digital WD_BLACK SN750 SE 1TB is DRAM-less. A DRAM cache holds the drive's mapping table — the index of where each block physically sits — so the controller places and finds data without an extra flash lookup. A DRAM-less drive borrows a little system memory (HMB) or a slice of its own flash instead, and is likelier to slow once a long run of random writes outlasts its fast cache.
NAND
NAND: Kingston NV2 1TB uses TLC and Western Digital WD_BLACK SN750 SE 1TB uses TLC. The tier is bits per cell — SLC, MLC, TLC and QLC from one to four — trading density against endurance and sustained-write speed: QLC is cheapest per gigabyte, TLC the mainstream balance, and the denser the cell the sooner sustained writes taper.
Which to buy
Western Digital WD_BLACK SN750 SE 1TB. It gives up nothing to the other on the measures the site tracks and leads on at least one, so there is no trade to weigh — the sections above show where the margin is.
