The Fanxiang S500 Pro is a solid-state drive in the M.2 2280 form factor. It is available in capacities ranging from 256 GB to 1 TB. This page reports specifications for the 512 GB variant. With the rest of the system, the Fanxiang S500 Pro interfaces using a PCI-Express 3.0 x4 connection. The SSD controller is the MAP1202A-F1C Cougar from MaxioTech, a DRAM cache is not available. Fanxiang has installed 128-layer TLC NAND flash on the S500 Pro, the flash chips are made by YMTC. To improve write speeds, a pseudo-SLC cache is used, so bursts of incoming writes are absorbed more quickly. The S500 Pro is rated for sequential read speeds of up to 3,200 MB/s and 3,000 MB/s write.
At its launch, the SSD was priced at 30 USD. The warranty length is set to two years, which is quite short for the SSD industry. Fanxiang guarantees an endurance rating of 320 TBW, a good value.

YMTC 128L Xtacking 2.0 cell architecture consists of two decks connected through deck-interface buffer layer which is the same process with KIOXIA 112L BiCS 3D NAND structure. Cell size, CSL pitch, and 9-hole VC layouts keep the same design and dimension (horizontal/vertical WL and BL pitches) with previous 64L Xtacking 1.0 cell. Total number of gates is 141 (141T) including selectors and dummy WLs for the TLC operation.
This layout has a 1x 4 Plane layout, each one lineup side by side
