Fikwot FX991 M.2 SSD 1TB NVMe SSD M2 2280 PCIe Gen 4x4

Bottom line: The Fikwot FX991 M.2 SSD 1TB NVMe SSD M2 2280 PCIe Gen 4x4: 7000MB/s rated reads clear Sony's 5500MB/s PS5 expansion requirement; main trade-off: 3D QLC NAND writes slower than TLC once the SLC cache fills.

Pros & Cons

Pros

  • ✓ 7000MB/s rated reads clear Sony's 5500MB/s PS5 expansion requirement
  • ✓ 5-year limited service with a 600TBW endurance rating
  • ✓ Graphite heatsink plus auto-adaptive thermal and power throttling
  • ✓ AES-256 hardware encryption, TRIM, and S.M.A.R.T. all supported

Cons

  • ✗ 3D QLC NAND writes slower than TLC once the SLC cache fills
  • ✗ 3000MB/s write ceiling is under half the 7000MB/s read rating
  • ✗ HMB design means no onboard DRAM cache
  • ✗ 600TBW is modest for a 1TB drive under heavy write workloads

Manufacturer description

The Fikwot FX991 1TB is a PCIe Gen 4x4 NVMe SSD in the standard M.2 2280 form factor, rated for sequential reads up to 7000MB/s and writes up to 3000MB/s. That read ceiling puts it comfortably past the 5500MB/s bar Sony sets for PS5 storage expansion, and Fikwot lists PS5 alongside laptops and desktops as supported hosts. The drive leans on Host Memory Buffer (HMB) rather than onboard DRAM, borrowing system memory for read/write caching, and pairs that with a dynamic SLC cache to keep boot times, multitasking, and game-asset loading responsive. A high-conductivity graphite heatsink plus…

SpecPicks Verdict

SpecPicks scored Fikwot FX991 M.2 SSD 1TB NVMe SSD M2 2280 PCIe Gen 4x4 using a rating × review-volume × price-fit model applied to published specs and reviews across the ssds & storage category. Fikwot's ssds & storage lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here. Judge it on the specification table and the price rather than on sentiment: check the figures that decide your use case, then put it side-by-side with two or three close alternatives in the Compare tool before clicking through.

Common buyer scenarios for ssds & storage of this kind: matching it to an existing build, replacing a failing part, or upgrading from a previous-generation equivalent. Check the spec table below against your current setup — particularly socket / form-factor / power-rating fields — and confirm compatibility on the retailer's listing before purchase. Prices and stock are set by the retailer and may have moved since this page was last updated.

Frequently Asked Questions

Will the Fikwot FX991 work in a PS5?

Fikwot lists PS5 storage expansion as a supported use. The drive is M.2 2280 PCIe Gen 4x4 and rated at 7000MB/s reads, above Sony's 5500MB/s minimum. Confirm heatsink clearance against your console's bay before buying.

How fast is the Fikwot FX991 1TB?

Fikwot rates it at up to 7000MB/s sequential read and up to 3000MB/s sequential write over PCIe Gen 4x4. Real-world write speeds drop once the SLC cache is exhausted, which is typical of QLC drives.

What warranty does the FX991 come with?

Fikwot advertises a limited service of up to 5 years or 600TBW, whichever comes first. Check the product listing for current terms and regional coverage.

Does this SSD have a DRAM cache?

No. The FX991 uses Host Memory Buffer (HMB), which borrows a slice of your system's DRAM for caching, plus a smart SLC cache. HMB requires host support, so performance can vary by platform.

Is QLC NAND a problem for gaming or everyday use?

For game loading and general desktop work, reads dominate and QLC handles them well at the drive's 7000MB/s rating. Sustained large file writes are where QLC slows most, so heavy video or backup workloads are the weak spot.

Key Features

  • [Lightning-fast Top Performance]: Fikwot FX991 M.2 SSD 1TB adopts NVMe protocol and PCIe Gen 4x4 specifications, and the maximum read and write speed can easily reach 7000MB/s and 3000MB/s. With lightning-fast speeds, the FX991 NVMe SSD can make your computer's systems and applications respond quickly, improving work efficiency.
