KingSpec P3 8TB vs PNY CS900 8TB
At least one of these has no price the site currently tracks, so what follows weighs specifications alone.
How these two compare
Sequential throughput
KingSpec P3 8TB reads at 580 MB/s and writes at 570 MB/s; PNY CS900 8TB reads at 560 MB/s and writes at 540 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.
NAND and warranty
On the flash itself: KingSpec P3 8TB's NAND is not stated, and PNY CS900 8TB 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. KingSpec P3 8TB carries a 3-year warranty and PNY CS900 8TB carries a 3-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.
