fanxiang S660 1TB PCIe 4.0 NVMe M.2 2280

The fanxiang S660 is a budget PCIe 4.0 NVMe SSD with a PS5-ready heatsink and 5000 MB/s reads. It's a decent performer for gaming, but US pricing at $230 puts it against much better drives like the Samsung 990 PRO and Crucial T500. Buy it only if you find it heavily discounted.

The S660 hits 5000 MB/s sequential reads and 4500 MB/s writes on paper. In practice, that's enough to load games quickly and move large files without feeling sluggish. It's not going to touch the 7000+ MB/s speeds of the Samsung 990 PRO or Crucial T500, but for a PS5 or a mid-range gaming PC, you probably won't notice the difference in day-to-day use. The drive is DRAM-less, which means it relies on SLC caching and HMB (host memory buffer) to keep things moving. That's fine for gaming and general use, but heavy sustained writes will eventually slow down once the cache fills.

One thing worth mentioning: some buyers have reported that the NAND inside is QLC, not TLC as advertised. That's a real concern if true, because QLC tends to have lower endurance and slower sustained write performance. Fanxiang claims SLC NAND in the listing, which is misleading at best. The 700TBW endurance rating is decent for a budget drive, but if it's actually QLC, that number feels optimistic. We can't verify the flash type from our data, but it's something to keep in mind if you plan to hammer this drive with constant writes.

Against the Samsung 990 PRO, the S660 loses on every performance metric. The 990 PRO hits 7450 MB/s reads and has a proper DRAM cache, plus Samsung's reputation for reliability. The Crucial T500 is similarly faster and often priced competitively. The WD Black SN850X is another step up, with excellent sustained performance and a proven track record in both PCs and PS5s. Even the Lexar NM1090 PRO and MK1UA T700 outclass the S660 on raw speed.

Where the S660 could win is price, but only if you find it heavily discounted. The included heatsink is a genuine advantage for PS5 users who don't want to buy one separately, but most competitors offer heatsink versions too. If you're deciding between this and a name-brand drive at the same price, there's no contest. The fanxiang only makes sense when it's noticeably cheaper.

Here's the thing: at $230 for 1TB, the S660 is not a good deal in the US. You can get a Crucial T500 or WD Black SN850X for similar money, and both are faster, more reliable, and from brands with actual track records. The S660 makes more sense in markets where fanxiang undercuts the big names significantly. In Europe, the EUR 170 price is a bit more palatable, but still not a screaming bargain. If you're on a tight budget and find this drive on sale, it's worth considering. At full US retail, skip it and buy something better.

The fanxiang S660 is a budget PCIe 4.0 NVMe SSD aimed squarely at PS5 owners and PC gamers who want fast storage without paying Samsung or WD prices. The 1TB model we're looking at promises up to 5000 MB/s reads and 4500 MB/s writes, and it ships with a heatsink in the box, which is a nice touch for console users. Pricing is all over the map depending on where you live, but in the US it's listed around $230, which puts it in a weird spot. That's not exactly cheap for a DRAM-less drive with a 700TBW endurance rating.

Fanxiang isn't a household name, but the S660 has racked up over 3,700 reviews on Amazon with a 4.6-star average. People searching for a PS5 SSD that won't break the bank will definitely stumble across this one. The question is whether it's actually a good deal or just a cheap drive with a heatsink attached.

Our database puts the S660 at 87th percentile for features, which makes sense given the included heatsink and PS5 compatibility. But speed lands at 72nd percentile, and endurance sits at a middling 57th. So it's not a top-tier performer, but it's not pretending to be one either.

Skip the S660 if you're in the US and paying anywhere near $230. At that price, the Samsung 990 PRO, Crucial T500, and WD Black SN850X are all better buys with faster speeds, DRAM caches, and more trustworthy specs. Content creators who do heavy sustained writes should also look elsewhere, since the DRAM-less design and possible QLC NAND will slow down under load. If you need a drive for professional work or frequent large file transfers, spend the extra money on a drive with proven endurance and consistent performance.

Should you buy the fanxiang S660? If you're in the US and paying $230, absolutely not. That's Samsung 990 PRO territory, and the 990 PRO is a better drive in every way. If you're in a market where the S660 is significantly cheaper than the competition, or you catch it on a deep sale, it's a serviceable budget option. The 5-year warranty and included heatsink add some peace of mind, and most buyers seem happy with real-world performance.

But the QLC question mark bothers us. If fanxiang is shipping QLC while advertising TLC, that's a trust issue. For a drive you're going to stuff with games and maybe important files, we'd rather spend a little more on a brand that doesn't play games with specs. The S660 is fine, not great, and only worth it at the right price.
