fanxiang S660 2TB PCIe 4.0 NVMe SSD with Heatsink: specs and who it suits

The fanxiang S660 is a PCIe 4.0 NVMe M.2 solid state drive with a built-in heatsink. The brand lists it for expanding PlayStation 5 storage, and also for use in PCs. This page covers what the specifications mean and what to check first.

PCIe 4.0 and 5000MB/s

PCIe 4.0 is the interface generation that supports speeds well beyond older Gen3 drives. fanxiang quotes speeds of up to 5000MB/s. Maximum speeds are sequential figures measured in ideal conditions, and they depend on the host device. Games benefit mainly through shorter load times, but the difference compared with a slower drive is often smaller in practice than the headline numbers suggest.

Why the heatsink matters

NVMe drives generate heat under sustained work, and when they get too hot they slow themselves down (thermal throttling). fanxiang says the heatsink keeps the S660 at lower temperatures during long, intensive use. The PS5 expansion bay has its own requirements for M.2 drives, including a heatsink option and limits on overall size, so check Sony's published storage requirements and the dimensions on this listing, which gives about 3.1 × 0.9 × 0.4 inches (79 × 23 × 10 mm) for the drive with its cooler. The height is the key figure: 0.4 inches is about 10 mm.

Capacity range

The S660 line is offered from 500GB to 4TB, according to the brand. This listing is the 2TB model. For game libraries, which can run to tens of gigabytes per title, a larger drive means fewer installs and deletions.

Beyond the console

fanxiang says the drive also connects to other platforms, including PCs. In a PC, it needs a free M.2 slot that supports NVMe; PCIe 4.0 speeds need a motherboard or laptop with PCIe 4.0 support, otherwise the drive will run at a lower speed on an older slot. Some laptops will not fit a drive with a heatsink, so check clearance.

Assurance

The brand lists a five-year quality assurance and says its support team is available. Read its terms.

Who it suits

It suits console owners who need more game storage and PC users with a PCIe 4.0 slot who want a fast second drive.

What to check before you buy

• Console requirements: compare the PS5's current M.2 specifications with the drive's size, speed and heatsink.
• Slot type: a PC slot must be M.2 with NVMe support.
• Clearance: the heatsink adds height, so measure.
• Capacity: confirm that 2TB is enough, since games keep growing.
• Setup: the console formats a new drive, and a PC may need disk setup.
• Backups: keep a copy of anything important before changing storage.
