Fanxiang S800 2TB: budget PCIe 4.0 with real capacity (2026)

Posted on August 08, 2026 by Raymond Chen

The Fanxiang S800 2 TB is a budget DRAM-less PCIe 4.0 NVMe rated at up to 7,300 MB/s reads with YMTC 232-layer TLC, sized for a proper game library on a tight budget.

Fanxiang S800 2TB: budget PCIe 4.0 with real capacity

Controller & Memory

Fanxiang is a Chinese budget brand that sells affordable SSDs, and the S800 is its mainstream PCIe 4.0 module. The 2 TB model pairs Maxio's MAP1602 controller with YMTC (Yangtze Memory) 232-layer 3D TLC NAND and no DRAM, using the Host Memory Buffer to hold the flash translation layer in system RAM. It is rated at 7,300 MB/s sequential reads and 6,800 MB/s writes over PCIe 4.0 x4, ambitious numbers for a budget drive.

The S800 ships in 1 TB, 2 TB, and 4 TB. The 2 TB is the middle and most practical capacity, sharing the same controller and NAND as its siblings and carrying a 1,400 TBW endurance rating, double the 1 TB's figure. It is a standard single-sided M.2 2280 card, so it drops into laptops and desktops with a PCIe 4.0 slot without clearance concerns.

As a DRAM-less design, the S800 leans on its SLC cache to reach its rated write speed, and like most budget drives the sustained figures trail the peak rating. The 2 TB's larger SLC cache holds sustained writes at full speed longer than the 1 TB's, which helps when moving large folders or installing big games. For booting, gaming, and everyday file work the drive is more than adequate, and the 2 TB capacity is its main draw: a lot of fast storage for a budget price.

S800 Performance & Benchmarks

The S800 2 TB is rated at 7,300 MB/s sequential reads and 6,800 MB/s writes over PCIe 4.0, figures shared across the line. No reliable random-IOPS figure is published for the drive, and the manufacturer rates the same peak throughput across all capacities.

  • Patriot Viper PV593 1 TB: 14,500 MB/s read, 14,000 MB/s write
  • Patriot Viper PV593 2 TB: 14,500 MB/s read, 14,000 MB/s write
  • Patriot Viper PV593 4 TB: 14,500 MB/s read, 14,000 MB/s write
  • Patriot Viper PV573 2 TB: 14,000 MB/s read, 12,000 MB/s write
  • Fanxiang S800 2 TB (this drive): 7,300 MB/s read, 6,800 MB/s write

Real-world results trail the rating, as is typical for budget DRAM-less drives on the Maxio MAP1602 platform. Writes run at full speed inside the SLC cache until it fills, then settle to the native TLC rate; the 2 TB's larger cache absorbs longer sustained transfers than the 1 TB before slowing. Reads, by contrast, stay close to the rating in everyday use.

For gaming and everyday use the difference is hard to notice. Game load times are bounded by the CPU and asset decompression once a drive clears about 3,000 MB/s, so the S800 feels as quick as a faster-rated drive in practice. The 2 TB's advantage is capacity, holding a full modern game library on one drive. Large sustained transfers and heavy write workloads are where the budget DRAM-less design shows; for a game library that rarely matters. It runs cool enough under light use, though sustained writes benefit from a motherboard heatsink.

Endurance, TBW & Warranty

Fanxiang covers the S800 2 TB with a five-year limited warranty, a strong term for a budget drive. Endurance is rated at 1,400 TBW on this model, which at a typical 20 GB per day of writes equates to roughly 192 years, so the flash will outlast the warranty in normal use. The rating scales with capacity, from 700 TBW on the 1 TB through 1,400 TBW here up to 2,800 TBW on the 4 TB, figures johnnylucky corroborates for the line at 2.8 PBW. Fanxiang rates the drive at around 2 million hours MTBF, a population statistic describing expected failures across a fleet rather than a guarantee for any single unit. Returns are handled through the retailer or Fanxiang depending on region, and the drive ships without a heatsink, so motherboard M.2 cooling is recommended.

Verdict: Is the S800 Worth It in 2026?

Buy the Fanxiang S800 2 TB for a budget build that wants a full-size game library or project archive on a single PCIe 4.0 drive, with 1,400 TBW of endurance and a five-year warranty for well under flagship money. Skip it when very large files are moved constantly, since the DRAM-less design settles to the native TLC rate once the SLC cache fills, or when brand familiarity and review coverage matter, where the Crucial P310 2 TB is the safer pick. The natural rivals are the Crucial P310 2 TB and Kingston NV2 2 TB, both budget Gen4 options. We rate the 2 TB S800 a reasonable large-capacity value drive, best suited to everyday, gaming, and archive use on a budget.

Frequently Asked Questions

Yes, for a budget gaming build the 2 TB S800 is a solid choice, and its main virtue is capacity, holding a full modern game library on one drive. Game load times are bounded by the CPU and asset decompression once a drive clears about 3,000 MB/s, so the S800's rated 7,300 MB/s reads feel as fast as a pricier drive in practice. The DRAM-less design is fine for gaming workloads, and the larger SLC cache keeps game installs and library transfers fast. It is a sensible pick when budget and capacity are the priorities.

It meets Sony's speed requirement but is not a recommended console upgrade because it ships without a heatsink. Sony requires an M.2 NVMe SSD with at least 5,500 MB/s reads and dimensions up to 110 by 25 by 11.25 mm including a heatsink; the S800's 7,300 MB/s rating clears the speed bar and the 2 TB capacity is practical, but the drive comes bare and a heatsink that fits the PS5's slot must be added. For a console, a drive bundled with a suitable cooler is the simpler, safer choice.

No. The S800 is a DRAM-less design that uses the Host Memory Buffer (HMB), borrowing a small portion of system RAM to hold the flash translation layer. This keeps the drive affordable, but it depends on system memory more than a DRAM-equipped module. In practice the impact shows mainly in sustained writes and heavy mixed workloads, where a DRAM-equipped drive holds higher throughput; for everyday booting, gaming, and file transfers the difference is hard to notice.

The 2 TB S800 is rated at 1,400 TBW, meaning it can handle 1,400 terabytes of total writes. At a typical 20 GB per day that works out to roughly 192 years, so the flash will outlast the five-year warranty in any realistic scenario. The rating scales with capacity, from 700 TBW on the 1 TB up to 2,800 TBW on the 4 TB. For a 2 TB game and system drive, 1,400 TBW is a strong, more-than-adequate figure for a budget model.

Not for light everyday use, but a heatsink is recommended for sustained workloads. The S800 ships without one, and like most budget DRAM-less drives it runs cool under normal use, so a bare install in a well-ventilated case is fine for booting and gaming. Under long sustained writes the controller warms up, and a motherboard M.2 heatsink keeps performance from thermal-throttling. Most modern motherboards include one, so fitting it is free insurance.

It is usable for light to moderate 4K editing on a budget, and the 2 TB capacity is a better fit for footage than the 1 TB. The drive's rated 7,300 MB/s reads are fine for scrubbing 4K timelines, and the larger SLC cache handles sustained captures and renders well before dropping to the native TLC rate. For serious video work a DRAM-equipped drive holds higher sustained throughput, but for light or occasional editing the 2 TB S800 offers a lot of space for the money.

Both are DRAM-less budget PCIe 4.0 drives with similar real-world performance. The S800 is rated a touch higher on peak reads at 7,300 MB/s versus the P310's 7,100 MB/s, and it offers a five-year warranty, while the Crucial has a more established brand and broader review coverage. Endurance figures are comparable for the class. For most budget buyers the Crucial is the safer, better-documented choice; the S800 is worth considering where it is cheaper.
