fanxiang S660 1TB PCIe 4.0 NVMe M.2

The fanxiang S660 is a budget PCIe 4.0 NVMe SSD that's PS5-ready with an included heatsink. It hits around 5000 MB/s reads and comes with a 5-year warranty and 700TBW endurance. It's not the fastest drive out there, but for gaming and everyday use, it gets the job done without breaking the bank.

The S660 hits around 5000 MB/s sequential reads and 4500 MB/s writes in our testing, which puts it at the 72nd percentile for speed among all drives in our database. That's above average, but not top tier. For context, the Samsung 990 PRO and WD SN850X both clear 7000 MB/s, so if you're chasing benchmark numbers, this isn't your drive. But for loading games, booting Windows, or moving large files around, the difference between 5000 and 7000 MB/s is honestly hard to notice outside of synthetic tests.

The DRAM-less design is the main performance caveat. The SLC cache is fast while it lasts, but once you push past it with sustained writes, speeds drop noticeably. For typical gaming and everyday use, you'll rarely hit that wall. The included heatsink helps keep thermals stable under load, which matters if you're stuffing this into a PS5 with limited airflow. Overall, the performance is solid for the price, just don't expect flagship numbers.

The Samsung 990 PRO and WD SN850X are the obvious benchmarks here, and both are faster, with sequential reads over 7000 MB/s. They also cost more, sometimes significantly more. The Crucial T500 splits the difference, offering near-flagship speeds at a more reasonable price. The Lexar NM1090 PRO and MSI SPATIUM M480 PRO are also in the mix, with the MSI drive being a particularly strong value pick if you can find it on sale.

Against the 990 PRO specifically, the S660 gives up about 2000 MB/s of sequential read speed and the DRAM cache. But in real-world gaming, the gap is much smaller than the spec sheet suggests. If you're building a PS5 storage expansion and don't want to spend flagship money, the S660 is a reasonable choice. If you're putting together a high-end PC build and want the fastest possible storage, the 990 PRO or SN850X are worth the extra cash.

At around $200 USD for the 1TB model, the S660 is priced like a mid-range drive but performs like one too. That's not a knock, it's just reality. You can find cheaper PCIe 4.0 drives, but they often skimp on warranty or endurance. The 5-year warranty and 700TBW rating add real peace of mind here. If you're in Europe, the EUR 170 price is more competitive, and the CAD 254 listing in Canada is about what you'd expect for this class. The value proposition really depends on what you're upgrading from. Coming from a SATA SSD or HDD, this is a massive jump. Coming from another PCIe 4.0 drive, it's more of a lateral move.

The fanxiang S660 is a budget PCIe 4.0 NVMe drive aimed at PS5 owners and anyone who wants fast storage without paying Samsung or WD prices. It's a DRAM-less design with SLC caching, rated for up to 5000 MB/s reads and 4500 MB/s writes. The 1TB version we're looking at usually lands around $200 USD, though pricing varies a lot by region. That puts it in a weird spot: cheaper than flagship drives, but not the absolute cheapest PCIe 4.0 option out there.

People searching for this drive usually want to know two things: is it good for PS5, and is it reliable? The short answer is yes on the PS5 front, the included heatsink (which you install yourself) keeps temps in check and the speeds clear Sony's 5500 MB/s recommendation closely enough that real-world load times feel fine. On reliability, the 5-year warranty and 700TBW endurance rating are solid for this price class, though the DRAM-less design means sustained writes can dip once the SLC cache fills.

We've seen a lot of these value-oriented drives come through our database, and the S660 sits in a decent spot. It's not going to blow anyone away on paper, but for a gaming drive or a secondary storage upgrade, it does the job without drama.

Skip the S660 if you're doing heavy sustained write workloads like 4K video editing or large file transfers on a regular basis. The DRAM-less design and QLC NAND will show their limits there. If you're building a high-end PC and want the absolute fastest storage, the Samsung 990 PRO or WD SN850X are better choices, just more expensive. And if you're looking for a portable drive, this isn't it, the portable score of 17.9/100 in our database is one of the weakest we've seen. For that use case, look at external SSDs instead.

Should you buy the fanxiang S660? If you need a PS5-compatible drive with a heatsink and don't want to pay Samsung or WD prices, yes, this is a solid pick. The 5-year warranty and 700TBW endurance rating are genuinely good for this price point, and the performance is more than adequate for gaming and everyday use.

But if you're chasing maximum speed or doing heavy sustained write workloads like video editing, look elsewhere. The DRAM-less design and QLC NAND (despite some listings claiming TLC) mean this drive has clear limits. For most people, though, those limits won't matter. It's a good drive at a fair price, just not a great one.
