Kingston KC600 2TB vs Western Digital WD Blue SA510 2TB
At least one of these has no price the site currently tracks, so what follows weighs specifications alone.

How these two compare
Sequential throughput
Kingston KC600 2TB reads at 550 MB/s and writes at 520 MB/s; Western Digital WD Blue SA510 2TB reads at 560 MB/s and writes at 520 MB/s. Both ride the SATA bus, which caps sequential transfer near 550 MB/s in either direction — the ceiling every SATA drive works against — so what more decisively separates them is sustained and random behaviour, the DRAM cache, and endurance.
Random access
Kingston KC600 2TB is rated 90.000 IOPS random read and 80.000 random write; Western Digital WD Blue SA510 2TB, 89.000 and 75.000. 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.
Endurance
Kingston KC600 2TB is rated for 1200 TBW and Western Digital WD Blue SA510 2TB for 700 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: Kingston KC600 2TB carries a DRAM cache, and the catalog does not state whether Western Digital WD Blue SA510 2TB 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: Kingston KC600 2TB uses TLC, and Western Digital WD Blue SA510 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: Kingston KC600 2TB uses the Silicon Motion SM2259 and Western Digital WD Blue SA510 2TB'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. Kingston KC600 2TB carries a 5-year warranty and Western Digital WD Blue SA510 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
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.
