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
Samsung 9100 Pro 2TB is $579.99 ($290.00 per TB); Western Digital WD_BLACK SN8100 2TB is $529.99 ($265.00 per TB).
NAND
On the flash itself: Samsung 9100 Pro 2TB uses TLC, and Western Digital WD_BLACK SN8100 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.
