How these two compare
Sequential throughput
fanxiang S500 Pro 2TB is rated 3500 MB/s read and 3000 MB/s write; Solidigm P41 Plus 2TB, 4125 MB/s read and 3325 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
fanxiang S500 Pro 2TB lists at $419.99, or $210.00 per TB; Solidigm P41 Plus 2TB at $628.87, or $314.44 per TB.
DRAM cache
the catalog does not state whether fanxiang S500 Pro 2TB carries a DRAM cache; Solidigm P41 Plus 2TB 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, controller and warranty
NAND: fanxiang S500 Pro 2TB uses QLC and Solidigm P41 Plus 2TB uses QLC. 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: fanxiang S500 Pro 2TB's controller is not stated, and Solidigm P41 Plus 2TB uses the Silicon Motion SM2269XT. 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: fanxiang S500 Pro 2TB does not state one, Solidigm P41 Plus 2TB carries a 5-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.
