# Fanxiang S800 1TB: budget PCIe 4.0 storage (2026)

The Fanxiang S800 1 TB is a budget DRAM-less PCIe 4.0 NVMe rated at up to 7,300 MB/s reads with YMTC 232-layer TLC, aimed at value builds and everyday upgrades.

Quick answer: Buy the Fanxiang S800 1 TB for a budget build or an older machine that wants PCIe 4.0-class speed without paying for a DRAM cache or a famous brand, and where 1 TB is enough for a boot drive and a moderate library. Skip it when very large files are moved regularly, 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 1 TB is the safer pick. The natural rivals are the Crucial P310 1 TB and Kingston NV2 1 TB, both budget Gen4 options. We rate the 1 TB S800 a reasonable value drive, best suited to light, everyday, and gaming use on a budget.

## Performance

The S800 1 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.

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, and a 1 TB drive's cache is smaller than the 2 TB's, so it holds sustained writes for less time. 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. Large sustained transfers and heavy write workloads are where the budget DRAM-less design shows; for a boot drive or a small 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 1 TB with a five-year limited warranty, a strong term for a budget drive. Endurance is rated at 700 TBW on this model, which at a typical 20 GB per day of writes equates to roughly 96 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 on the 2 TB 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.

## Pros and Cons

**Pros:**

- Up to 7,300 MB/s rated reads on PCIe 4.0
- YMTC 232-layer TLC NAND
- 700 TBW endurance rating

- Sustained writes settle to the TLC rate


## Verdict

Buy the Fanxiang S800 1 TB for a budget build or an older machine that wants PCIe 4.0-class speed without paying for a DRAM cache or a famous brand, and where 1 TB is enough for a boot drive and a moderate library.

## Frequently Asked Questions

### Is the Fanxiang S800 1 TB good for gaming?

Yes, for a budget build the 1 TB S800 is a serviceable gaming 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 1 TB capacity fits a moderate library of modern titles, so it works well as a boot drive with a game collection. It is a sensible choice when budget is the priority, though a larger capacity gives more room as libraries grow.

### Is the Fanxiang S800 1 TB compatible with the PS5?

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, 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.

### Does the Fanxiang S800 have a DRAM cache?

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.

### What is the TBW endurance of the Fanxiang S800 1 TB?

The 1 TB S800 is rated at 700 TBW, meaning it can handle 700 terabytes of total writes. At a typical 20 GB per day that works out to roughly 96 years, so the flash will outlast the five-year warranty in any realistic scenario. The rating scales with capacity, from 1,400 TBW on the 2 TB up to 2,800 TBW on the 4 TB. For a 1 TB boot and game drive, 700 TBW is a strong, more-than-adequate figure for a budget model.

### Does the Fanxiang S800 need a heatsink?

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.

### Is the Fanxiang S800 1 TB good for video editing?

It is usable for light 4K editing, but 1 TB is limiting for footage and the DRAM-less design shows on sustained writes. The drive's rated 7,300 MB/s reads are fine for scrubbing 4K timelines, and the SLC cache handles short bursts well. However, long renders and large transfers drop to the native TLC rate once the cache fills, which is slower than a DRAM-equipped drive. For serious video work a larger DRAM-equipped drive is the better choice; the S800 suits light or occasional editing.

### How does the Fanxiang S800 1 TB compare to the Crucial P310 1 TB?

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.
