Capacity and interface

The FANXIANG S501Q is a 2TB internal SSD built on the M.2 2280 form factor and a PCI-Express 3.0 x4 NVMe link. It targets laptop and desktop users who want a large, single-volume upgrade for everyday workloads and game libraries.

Sustained write behaviour

The drive uses 3D NAND QLC with an SLC cache to absorb burst traffic, then settles to the native QLC write rate once the cache fills. Its 640TB TBW rating and 1,500,000-hour MTBF reflect the endurance envelope for long-term mixed read and write activity.

Thermals and power

A graphite heat-dissipation sticker is included to spread heat across the controller and NAND packages. The drive is rated for 0°C to 70°C operating temperature and -25°C to 85°C storage temperature, indicating typical power draw and thermal output for a Gen 3 x4 NVMe device without a dedicated heatsink.

Highlights

Questions about this item

Does the 2 TB S501Q run hot or draw extra power during all‑day use?

The drive includes graphite heat‑dissipation stickers to control temperature, operates from 0 °C to 70 °C and uses the PCIe 3.0 x4 interface without a heatsink.

What must my motherboard provide for this M.2 2280 NVMe drive to work?

An M.2 slot wired for PCIe 3.0 x4 NVMe; the drive is 22 mm wide and 2.40 mm high.

Will this PCIe 3.0 x4 SSD run at full speed in a PCIe 2.0 slot?

It will function but speeds are limited to the PCIe 2.0 x4 ceiling, below the 3600 MB/s read and 2700 MB/s write ratings.
