The Fanxiang S501 512GB NVMe SSD is a solid-state drive that uses the NVMe interface and is based on the M.2 2280 form factor. It uses a PCIe Gen3 x4 interface, which provides a maximum bandwidth of 32 Gb/s. It is also compatible with PCIe Express 3.1 and NVMe 1.3.

This SSD uses 3D NAND technology, which allows for higher storage density and endurance compared to traditional 2D NAND. It also supports S.M.A.R.T., TRIM, and garbage collection.

With sequential read speeds of up to 2,150MB/s and write speeds of up to 1,800MB/s, it is designed to provide high performance and fast data transfer rates.

It is typically uses one PCI-E lane for its operation. Please note that, even though the Fanxiang S501 512GB NVMe uses one lane, it does not necessarily mean it will consume that lane entirely, as modern NVMe drives can share the lane with other devices.
