In these crazy times, SSD prices have skyrocketed to unbelievable levels. The well-known brands are either pricing their high-end models out of reach or leaving their mainstream options permanently out of stock. But if you take a closer look at the market, a few lesser known names have stepped in to fill the gap—one of which is what we’re taking a look at today. The Fanxiang S880E 1TB sits squarely in that budget-friendly Gen4 territory, aiming to deliver fast read speeds without demanding a premium price tag.
We ran the drive through our usual suite of benchmark tools to see how it performs in sequential throughput, random I/O, and thermal management.
Specifications & Hardware Profile
The Fanxiang S880E 1TB comes in a single-sided M.2 2280 form factor. It operates over the PCIe 4.0 x4 interface using the NVMe 2.0 protocol.
- Interface: PCIe 4.0 x4, NVMe 2.0
- Firmware: GTC7740f
- Formatted Capacity: ~931.51 GiB (1000.2 GB total host space)
- Features: S.M.A.R.T., TRIM, Volatile Write Cache
- Architecture: DRAM-less with Host Memory Buffer (HMB) support
Hardware Teardown & Component Analysis
Peeling back the heat spreader sticker reveals the underlying PCB layout. The hardware choices shed light on how Fanxiang managed to hit high PCIe 4.0 performance at a lower price point:
- SSD Controller: Maxio MAP1602A-F3C
- Architecture: Quad-core ARM Cortex-R5, built on a power-efficient 12nm process.
- Design: 4-channel, DRAM-less architecture relying on NVMe 1.4/2.0 Host Memory Buffer (HMB) tech.
- Impact: The MAP1602A controller is renowned for low power consumption and high energy efficiency. Operating without a power-hungry physical DRAM chip keeps overall heat output low while delivering close to 7,000 MB/s sequential throughput.
- NAND Flash Memory: LCQM256G5NBB5B1
- Configuration: 4 x 256GB NAND packages on a single-sided PCB to complete the 1TB capacity.
- Flash Technology: High-density 3D QLC NAND configured for 4-channel operation under the Maxio controller.
- Single-Sided Layout: Keeping all ICs on the top side makes this drive thin enough for ultra-thin laptops and easy mounting on motherboard M.2 slots with pre-installed heatsinks.
Synthetic Benchmarks Analysis
CrystalDiskMark 8.0.6: Peak Burst Throughput
CrystalDiskMark tests the drive under ideal, peak-burst conditions using pseudo-random/compressible data across a 1GiB test span.
- SEQ1M Q8T1 Read: 6,946.25 MB/s
- SEQ1M Q8T1 Write: 5,894.70 MB/s
- RND4K Q32T16 Read: 3,828.18 MB/s (~957K IOPS)
- RND4K Q32T16 Write: 3,054.54 MB/s (~763K IOPS)
- RND4K Q1T1 Read: 78.13 MB/s
- RND4K Q1T1 Write: 284.92 MB/s
Deep Dive: The sequential throughput figures show that the Maxio MAP1602A controller fully saturates four lanes of PCIe 4.0 bandwidth. While hitting ~6,946 MB/s read and ~5,894 MB/s write looks great on paper, what matters more for daily desktop usability is the low-queue random performance.
The 78.13 MB/s 4K Q1T1 read speed is a standout figure for a DRAM-less drive. Many budget Gen4 drives struggle to crack 60–65 MB/s in single-threaded 4K reads due to the latency penalty of lacking dedicated DRAM. Leveraging Host Memory Buffer (HMB) effectively keeps access times low, meaning OS booting, navigating Windows Explorer, and launching games will feel virtually identical to higher-tier drives with onboard DRAM.
On the high-queue side, achieving over 950K read IOPS shows that the controller won’t bottleneck under multi-threaded queue pressure, such as heavy background asset streaming during modern PC gaming.
AS SSD Benchmark 2.0: Uncompressible Data & Controller Stress
Unlike CrystalDiskMark, AS SSD uses completely uncompressible data, stripping away any speed advantages a controller might gain from real-time compression algorithms.
- Sequential Read: 5,941.48 MB/s
- Sequential Write: 5,173.53 MB/s
- 4K Low-Queue Read / Write: 67.93 MB/s / 232.74 MB/s
- 4K-64Thrd High-Queue Read / Write: 2,373.11 MB/s / 2,512.63 MB/s
- Acc. Time (Read / Write): 0.018 ms / 0.067 ms
- Overall Score: 7,811 (Read: 3,035 | Write: 3,263)
Deep Dive: AS SSD always paints a harsher, more conservative picture than CrystalDiskMark. The sequential drop to ~5,941 MB/s read and ~5,173 MB/s write highlights how the drive behaves when handling already-compressed media files (like ZIP archives, modern video codecs, or encrypted game installs).
The access times—0.018 ms for reads and 0.067 ms for writes—are exceptionally tight. Low read latency confirms that HMB caching is successfully fetching look-up tables from system RAM without inducing notable delay. Furthermore, crossing the 7,800 total point threshold puts the S880E ahead of older flagship PCIe 3.0 drives and positions it at the upper end of mainstream Gen4 DRAM-less competitors.
ATTO Disk Benchmark 4.01: Block Size Scaling & pSLC Stability
ATTO tests performance across a spectrum of file transfer sizes (512B to 64MB) at a queue depth of 4, providing a clear picture of how the controller handles small file fragments versus large sequential streams.
- Small File Operations (512B to 4KB): Writes scale rapidly from 68.15 MB/s to 1,016.64 MB/s. Reads scale from 67.42 MB/s to 993.20 MB/s.
- Mid to Large Block Operations (1MB to 64MB): Throughput levels out into a consistent plateau, holding steady at ~6.58 GB/s read and ~5.46 GB/s write from 4MB upward.
Deep Dive: The ramp-up curve in ATTO is clean. SSD controllers often display erratic dips between 4KB and 64KB block sizes if the flash translation layer (FTL) management struggles with block boundaries. Here, the S880E scales smoothly without any stuttering.
Crucially, the write performance maintains a completely flat line from 2MB through 64MB without dropping off during the test run. This indicates that ATTO’s 256MB test payload fits entirely inside the dynamic pSLC (pseudo-SLC) cache buffer, allowing the drive to sustain peak write throughput without falling back to raw TLC write speeds during short-to-medium length transfers.
Thermal Performance
During our benchmarking loop, we monitored drive temperatures via HWiNFO and CrystalDiskInfo.
- Idle Temperature: ~41°C
- Peak Load Temperature: 54°C (across internal sensors 1 through 3)
Thermal Analysis: Gen4 SSDs are known to run hot, often reaching thermal throttling points (typically 70°C+) when pushed hard without heavy heatsinks. The combination of the 12nm Maxio MAP1602A controller and a single-sided NAND layout allows the S880E to peak at just 54°C under sustained synthetic load. The three internal temperature sensors remained well-balanced (Drive Temp 1 & 2 at 54°C, Temp 3 at 49°C), confirming no localized hotspots on either the controller or flash ICs. This efficient thermal profile makes it suitable for tight spaces like laptops or PS5 internal expansion slots without requiring heavy aftermarket cooling hardware.
Final Verdict
Ultimately, judging this drive isn’t just about performance—it’s about price-to-performance ratio. To justify the trade-off, it needs to be priced well below a solid TLC alternative. If you’re a typical user who mainly reads files, keeps a big library, and only writes a few gigabytes a day, you’ll never breach the 240 GB cache. To you, this will feel like a fast, reliable drive. But for creators editing video or moving massive project files, sustained speeds matter, and as the test results show, hitting that cache limit hurts. It’s either a bargain or a bottleneck, depending entirely on what you do with it. As such, it stands as a practical choice for budget desktop builds, game storage expansion, or a secondary drive.
Pros:
- Maxio MAP1602A controller delivers strong efficiency and low operating temperatures
- Strong sequential read/write throughput approaching 7,000 / 5,900 MB/s
- Impressive 78 MB/s 4K single-queue random read speed despite being DRAM-less
- Clean block-size scaling in ATTO without controller instability or stuttering
- Runs cool (54°C peak under load), eliminating thermal throttling concerns
- Single-sided M.2 2280 form factor fits easily into laptops and thin enclosures
- Exceeds PS5 minimum read speed requirements (~5,500 MB/s)
Cons:
- DRAM-less design relies on Host Memory Buffer (HMB); sustained continuous writes beyond the pSLC cache limit will result in speed drops
