How these two compare
Sequential throughput
Lexar NS100 2TB is rated 550 MB/s read and 500 MB/s write; PNY CS900 2TB, 550 MB/s read and 530 MB/s write. The SATA link tops out around 550 MB/s each way, and both work against that ceiling; the more telling differences between SATA drives are how each holds up under sustained load, whether it carries a DRAM cache, and how much writing it is rated to take.
Price
Lexar NS100 2TB lists at 215,67 €, or 107,84 € per TB; PNY CS900 2TB at 248,20 €, or 124,10 € per TB.
NAND, controller and warranty
NAND: Lexar NS100 2TB uses TLC and PNY CS900 2TB 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. On the controller: Lexar NS100 2TB uses the Marvell 88NV1120, and PNY CS900 2TB's controller is not stated. It is the chip handling error correction, wear-levelling and where each write lands — much of how a drive holds up under load — even if the part number on its own tells you little. On the cover: Lexar NS100 2TB carries a 3-year warranty, PNY CS900 2TB carries a 3-year warranty. The length is the maker's own vote of confidence, and on an SSD it tends to track the endurance rating — a longer warranty usually meaning more rated writes.
