Pros & Cons

Pros

  • ✓ Sequential reads up to 550MB/s, close to the SATA III 6Gb/s limit
  • ✓ SLC caching speeds up boot, app launches and game loads
  • ✓ 3D NAND TLC flash rated for 40TBW of total writes
  • ✓ 3-year service, with screws and a screwdriver in the box
  • ✓ M.2 2280 drive with no moving parts, so it handles shock better

Cons

  • ✗ M.2 SATA (AHCI) only: will not work in NVMe-only slots
  • ✗ 128GB fills fast with a modern OS plus a few games
  • ✗ 420MB/s sequential writes trail the 550MB/s read speed
  • ✗ Much slower than PCIe NVMe drives that fit the same 2280 slot

Manufacturer description

The fanxiang S201 128GB M.2 SATA SSD is a low-cost way to replace a slow hard drive or bring an older laptop or desktop back into use. It uses the SATA III 6Gb/s interface and reaches sequential speeds of up to 550MB/s read and 420MB/s write, so boot times, app launches and game loads drop compared with a spinning disk. Intelligent SLC caching handles bursts of activity, such as opening programs, saving files and short transfers. The drive uses 3D NAND TLC flash rated for 40TBW of total writes. With no moving parts, the SSD resists shock better than a mechanical drive, which matters in a…

Frequently Asked Questions

Will the fanxiang S201 work in an NVMe M.2 slot?

Only if the slot also supports M.2 SATA (AHCI). The S201 is a SATA drive, not NVMe (PCIe), so it will not work in NVMe-only slots. Check your motherboard or laptop manual to confirm the slot supports M.2 SATA before you buy.

How fast is the fanxiang S201 128GB SSD?

It uses the SATA III 6Gb/s interface and is rated for sequential speeds of up to 550MB/s read and 420MB/s write. SLC caching speeds up short bursts such as booting, opening programs and loading games.

What size is this SSD, and will it fit my laptop?

It is an M.2 2280 drive, meaning 22mm wide and 80mm long. It fits laptops, desktops and all-in-ones that have an M.2 2280 slot supporting SATA (AHCI) drives.

How long will the fanxiang S201 last?

The drive uses 3D NAND TLC flash rated for up to 40TBW (terabytes written). That is plenty for a boot drive or everyday use, but it is modest for constant heavy writes such as video editing scratch space.

Which operating systems does it support, and what comes in the box?

fanxiang lists compatibility with Windows 7, 8, 10 and 11. The package includes installation screws and a screwdriver, and the drive comes with a 3-year service commitment. Check the product listing for full warranty terms.
