Pros & Cons

Pros

  • ✓ Rated up to 2,050 MB/s read on PCIe Gen3x4, about 5x SATA III throughput
  • ✓ M.2 2280 fits most desktop boards and M.2 NVMe laptops
  • ✓ 3D NAND cuts power draw and OS/game load latency
  • ✓ Built-in LDPC ECC error correction guards against read errors

Cons

  • ✗ Write speed tops out at 800 MB/s, far below the 2,050 MB/s read figure
  • ✗ fanxiang states the drive does not work in a PS5
  • ✗ Gen3x4, not Gen4 or Gen5, so newer boards leave bandwidth unused
  • ✗ 256GB holds only a handful of modern game installs

Manufacturer description

The fanxiang S501 is a 256GB NVMe drive built for the job most people actually need a second M.2 for: getting an aging laptop or budget desktop off SATA without rebuilding the whole machine. It runs on a PCIe Gen3x4 interface with 3D NAND, and fanxiang rates it at up to 2,050 MB/s sequential read and 800 MB/s write, which the brand positions as roughly five times the throughput of a SATA III connection. In practice that shows up as shorter Windows boots, faster game level loads, and less waiting on large project files in video or design work. Fit is straightforward: the M.2 2280 form factor…

Frequently Asked Questions

How fast is the fanxiang S501 256GB?

fanxiang rates it at up to 2,050 MB/s sequential read and 800 MB/s sequential write over its PCIe Gen3x4 interface, which the brand describes as roughly five times SATA III transfer performance.

Will this SSD work in a PS5?

No. fanxiang states directly in the product listing that this drive does not work in a PS5. If you need console storage expansion, look at a Gen4 drive rated for PS5 use instead.

Is 256GB enough storage for gaming?

It is enough for Windows plus a few titles, not a full library. Many buyers use the 256GB S501 as a boot and application drive and keep large game installs on a second, higher-capacity disk.

What systems is the fanxiang S501 compatible with?

It uses the M.2 2280 form factor and fits motherboards, desktops, and laptops with an M.2 NVMe slot. fanxiang lists compatibility with Windows 8, 10, 11, and later versions.

What warranty does fanxiang offer on the S501?

Warranty terms are not listed in the product specifications shown here. Check the current Amazon listing or fanxiang's support page for the warranty period and claim process before purchasing.
