fanxiang S660 1TB PCIe 4.0 NVMe SSD with Heatsink: features and who it suits

The fanxiang S660 is an M.2 NVMe solid-state drive that uses the PCIe 4.0 interface, sold here in a 1TB version with a heatsink fitted. fanxiang lists it as a PlayStation 5 storage upgrade that also works in PCs. Here is what the main specs mean and what to confirm before fitting a drive like this.

What PCIe 4.0 and 5000MB/s mean

NVMe drives connect directly to the PCIe bus rather than through the older SATA interface, which is capped at about 550MB/s. PCIe 4.0 doubles the bandwidth of PCIe 3.0 per lane, and fanxiang rates the S660 at speeds of up to 5000MB/s. That is a best-case sequential figure; everyday loading times depend on the game, the console or computer, and how much the drive is doing at once.

Small-file performance and sustained writes often matter more for real use than the headline number, and the listing gives only the peak figure.

Using it with the PS5

fanxiang describes the S660 as suited to the PS5 for faster game launches and more room for a game library. The PS5's expansion slot expects an M.2 NVMe drive that meets Sony's published requirements, including PCIe 4.0 support and a heatsink for cooling, so confirm the drive's specs against Sony's current guidance and the console's physical size limits before buying.

The heatsink

NVMe drives can slow themselves down (throttle) when they get hot during long transfers. fanxiang says the heatsink design keeps the drive at low temperatures in long, intensive use. A heatsink is also what the PS5 slot expects. On a desktop PC, check that the motherboard's own M.2 cover, if any, still fits over a drive with a heatsink attached.

Capacities and use in a PC

The S660 line is listed in capacities from 500GB to 4TB; this page covers the 1TB model. Besides the console, fanxiang says it works across platforms including PC, so it can serve as a boot or game drive in a desktop with a free PCIe 4.0 M.2 slot. Laptops are less predictable because of height limits, so check the clearance. In a PCIe 3.0 slot, an NVMe drive typically still works but runs at the slower interface speed.

Support

fanxiang lists a five-year quality assurance and an after-sales support team. Read the actual terms of the warranty before relying on it.

What to check before you buy

• Form factor: confirm that the slot is M.2 2280 and that the drive with heatsink fits in the available height.
• Console requirements: check the PS5's current specifications for supported drive sizes and speeds.
• Motherboard support: make sure the slot is NVMe and PCIe 4.0 if you want full speed.
• Capacity planning: modern games can be large, so consider how many you want installed at once.
• Backups: keep important files backed up, whatever the drive.
• Installation: switch off and unplug first, and follow the console or motherboard manual.
