The Fanxiang S770M is a solid-state drive in the M.2 2280 form factor, launched in 2022. It is available in capacities ranging from 1 TB to 4 TB. This page reports specifications for the 2 TB variant. With the rest of the system, the Fanxiang S770M interfaces using a PCI-Express 4.0 x4 connection. The SSD controller is the IG5236 (Rainier) from InnoGrit, a DRAM cache chip is available. Fanxiang has installed 176-layer TLC NAND flash on the S770M, the flash chips are made by Micron. To improve write speeds, a pseudo-SLC cache is used, so bursts of incoming writes are absorbed more quickly. Thanks to support for the fast PCI-Express 4.0 interface, performance is excellent. The S770M is rated for sequential read speeds of up to 7,400 MB/s and 6,800 MB/s write.
At its launch, the SSD was priced at 147 USD. The warranty length is set to five years, which is an excellent warranty period. Fanxiang guarantees an endurance rating of 2000 TBW, a good value.
