PCIe 3.0 NVMe 256GB

The FANXIANG S500 256GB is an M.2 2280 internal SSD using a PCIe 3.0 x4 interface and 3D NAND TLC flash. It targets everyday computing workloads on laptops and desktops that support NVMe. The drive delivers up to 2800 MB/s sequential read and 2000 MB/s sequential write. Rated endurance is 160 TBW with a 2,000,000-hour MTBF.

Sustained thermal behaviour

Without a heatsink the controller relies on the motherboard slot airflow to shed heat during long writes. The 4.00 mm single-sided profile keeps the drive within the 0 °C to 70 °C operating window in typical chassis. LDPC error correction and wear-leveling maintain data integrity as temperatures rise. Performance remains consistent until thermal limits trigger throttling.

Upgrade from SATA SSDs

Replacing a 2.5-inch SATA SSD with this NVMe drive removes the 6 Gb/s bottleneck and cuts boot and application load times. The jump is worth it when the platform has an M.2 2280 slot wired for PCIe 3.0 x4 and the user needs 256 GB of low-latency storage. Older systems limited to SATA or PCIe 2.0 will not see the full speed benefit.

Questions about this item

Will this drive fit in a standard laptop M.2 2280 slot?

Yes, the drive uses the M.2 2280 form factor measuring 22.00mm wide by 80.00mm long and 4.00mm tall, matching the standard slot dimensions.

Does the 256GB model reach the 3500MB/s read speed mentioned in the highlights?

No, the 256GB capacity is rated for up to 2800MB/s sequential read and 2000MB/s sequential write; the higher 3500MB/s figure applies to the 1TB model.

Is a heatsink required for this SSD in a typical desktop build?

The drive ships without a heatsink and is rated for 0°C to 70°C operating temperature; most motherboards provide sufficient airflow, but a motherboard heatsink can be added if desired.
