fanxiang S880 NVMe SSD Review: Budget PCIe 4.0 Speed Without the Brand Tax

Most shoppers looking at a $60–$80 1TB PCIe 4.0 drive are asking one question: Is this too good to be true? The fanxiang S880 sits in that crowded budget tier where names like Crucial P3 Plus and WD Black SN770 dominate. But fanxiang isn’t just another no-name — they’ve been quietly shipping SSDs for years, and the S880 is their attempt to undercut the big boys on raw sequential numbers.

Here’s the honest breakdown after digging through specs, user benchmarks, and 220 Amazon ratings.

What You Actually Get

The box is minimal: the drive itself in a clamshell, a basic paper manual, and nothing else. No screw, no heatsink, no software download card. The S880 ships in the standard M.2 2280 form factor — 80mm long, 22mm wide, and critically, single-sided with all NAND on one side. That matters if you’re upgrading a thin ultrabook or a PS5, where double-sided drives sometimes don’t fit.

The drive uses a Phison PS5021 controller with 3D TLC NAND and a DRAM-less HMB (Host Memory Buffer) design. That means it borrows a chunk of your system RAM for its mapping table instead of carrying dedicated cache chips. It’s a cost-cutting move, but it doesn’t automatically make the drive slow — it just changes how it behaves under load.

Real-World Performance

The S880’s headline number is 7,400 MB/s sequential reads. In practice, most users report 6,800–7,200 MB/s on CrystalDiskMark with a modern Ryzen or Intel platform. That’s right in line with drives costing 30% more. Writes land around 5,800–6,300 MB/s, which is solid but less impressive.

Here’s where it gets interesting. The S880 has a pseudo-SLC cache that absorbs bursts of writes at full speed. For a typical game install or file copy under 200GB, you won’t notice any slowdown. But push a massive 400GB+ transfer and the drive drops to raw TLC speeds — around 1,000–1,200 MB/s. That’s still faster than most SATA SSDs, but it’s a real drop.

One Amazon reviewer summed it up: “Copied my Steam library over — first 150GB flew, then it throttled noticeably. For gaming, you’ll never notice. For video editing, get something with a real DRAM cache.”

Where It Shines

Gaming workloads. Game loading times depend more on random read performance than sequential throughput. The S880’s 4K random reads are competitive with drives twice the price. In practice, that means faster level loads in Starfield, quicker texture pops in Cyberpunk 2077, and snappier DirectStorage performance on titles that support it.

Value per gigabyte. At typical street pricing, the 1TB S880 undercuts Samsung’s 980 Pro and WD’s SN770 by 15–20%. You’re paying for performance, not brand marketing.

Thermals. The single-sided design runs cooler than many dual-sided drives. Users report idle temps around 35–40°C and load temps of 55–65°C with decent airflow. Without a heatsink, sustained writes will push it toward 75°C and trigger throttling — that’s worth planning for.

Where It Falls Short

The DRAM-less design is the elephant in the room. For most home users, HMB works fine. But if you’re running heavy multitasking — several VMs, large database files, or constant 4K video scrubbing — the S880 can stutter where a DRAM-equipped drive wouldn’t. One reviewer noted: “Works great for games. Struggled when I had Photoshop, Premiere, and 20 browser tabs open. Occasional hitching.”

No heatsink included. On a desktop with good airflow, you’re fine. In a PS5 or a cramped laptop, you’ll want to add an aftermarket heatsink ($10–15) to avoid thermal throttling during extended sessions.

Warranty support. Fanxiang offers a 5-year warranty, but some users report slower-than-expected RMA responses. Keep your receipt and be prepared for a bit of back-and-forth if something fails.

Who Should Buy This

Buy it if: You’re building a gaming rig on a budget, upgrading a laptop, or adding a secondary game/library drive to a PS5. The S880 delivers 90% of the performance of premium drives at 70% of the price.

Skip it if: You’re a content creator doing heavy sustained writes, run a database server, or need guaranteed thermals in a constrained chassis. Spend the extra $20–30 on a drive with DRAM cache and a bundled heatsink.

FAQ

Q: Is the fanxiang S880 compatible with PS5? Yes, it meets the PCIe 4.0 and capacity requirements. The single-sided design fits the PS5’s M.2 slot. You’ll need to add a heatsink — the drive doesn’t include one — and the PS5’s 1TB minimum means the 500GB version won’t work.

Q: Does the S880 work in older PCIe 3.0 slots? Yes, it’s backward compatible. You’ll get PCIe 3.0 speeds (around 3,500 MB/s reads), which is still a massive upgrade over SATA SSDs. Just don’t expect full 7,400 MB/s unless your motherboard supports PCIe 4.0.

Q: How long will this drive last? The 1TB model is rated for 600 TBW (terabytes written). That’s roughly 300GB of writes per day for five years — far more than typical gaming or office use. Realistically, you’ll upgrade your system before you wear this out.

The Verdict

Rating: 4.2/5

The fanxiang S880 is proof that budget PCIe 4.0 doesn’t have to mean budget performance. For gamers and general users, it’s a legitimate steal. The DRAM-less design and missing heatsink are genuine limitations, but they only matter if your workload pushes sustained writes or heavy multitasking.

Buy it if: You want near-flagship speeds without the flagship price tag, and your use case is gaming, general storage, or a PS5 upgrade.

Skip it if: You need guaranteed sustained write performance or run memory-hungry professional workloads. Those buyers should look at a Samsung 980 Pro or WD SN850X.

For everyone else — this is one of the better budget NVMe drives on the market right now. Just grab a cheap heatsink while you’re at it.
