Capacity and fit

The FANXIANG S501Q is a 512GB internal SSD built in the M.2 2280 form factor for laptops and desktops with an M.2 slot. It uses a PCIe 3.0 x4 interface and NVMe protocol to deliver solid-state speed for everyday computing.

Throughput and endurance

Sequential reads reach up to 3200 MBps while writes top out at 1450 MBps, so large file transfers and game loads finish quickly. The QLC 3D NAND with SLC caching handles typical workloads well, and the 160TB TBW rating gives ample headroom for years of consumer use.

Thermals and power

Graphite heat-dissipation stickers help manage temperature during sustained transfers without adding a heatsink or extra height. The drive operates from 0°C to 70°C and stores safely between -25°C and 85°C, drawing only modest power thanks to the efficient PCIe 3.0 x4 controller.

Questions about this item

Will the 512GB S501Q work in my laptop that only has a PCIe 3.0 x4 M.2 slot?

Yes, the S501Q uses a PCIe 3.0 x4 interface and the standard M.2 2280 form factor, so it fits any laptop or desktop motherboard with that slot.

How can I verify the S501Q is delivering its rated 3200 MBps read and 1450 MBps write speeds after installation?

Run a benchmark tool such as CrystalDiskMark or AS SSD on the fresh drive; sequential results should approach the 3200 MBps read and 1450 MBps write figures.

Does the S501Q box include the M.2 mounting screw and a screwdriver, or do I need to buy them separately?

The package includes both the installation screw and a small screwdriver, so no extra hardware is required.
