Manufacturer description
The Fikwot FX991 is a 500GB M.2 2280 NVMe SSD built on PCIe Gen 4x4, rated for sequential reads up to 6300MB/s and writes up to 3100MB/s. That read figure puts it in genuine Gen 4 territory rather than the Gen 3 speeds many budget drives settle for, which shows up most clearly in boot times, application launches, and pulling large game assets off the drive. Fikwot pairs 3D QLC NAND with Host Memory Buffer (HMB) and a dynamic SLC cache, so the FX991 borrows system DRAM instead of carrying its own — a DRAM-less design that keeps cost down while still handling multitasking and load-heavy…
SpecPicks Verdict
SpecPicks scored Fikwot FX991 M.2 SSD 500GB 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.

Frequently Asked Questions
Will the Fikwot FX991 work in a PS5?
Yes. Fikwot lists PS5 storage expansion as a supported use case, and the drive is the standard M.2 2280 form factor with PCIe Gen 4x4. Note that at 500GB it holds only a handful of current-gen titles, so check your library size before buying.
How fast is the Fikwot FX991 500GB?
Fikwot rates it at up to 6300MB/s sequential read and up to 3100MB/s sequential write over PCIe Gen 4x4. Actual speeds depend on your motherboard's M.2 slot generation - a Gen 3 slot will cap it well below the rated read.
Does the FX991 have DRAM?
No. It is a DRAM-less drive that uses Host Memory Buffer (HMB) to borrow system RAM for caching, plus a dynamic SLC cache. HMB requires host support, so performance can vary between systems.
What warranty does Fikwot offer on the FX991?
Fikwot states a limited service period of up to 5 years or 300TBW, whichever comes first, for the FX991 500GB. Check the current product listing for the exact terms that apply to your region.
Does it need a separate heatsink?
The FX991 ships with a high-conductivity graphite heatsink and auto-adaptive temperature adjustment, which Fikwot says keeps read speeds near peak under high load. PS5 installs still require the console's own M.2 bay heatsink clearance to be respected.
Key Features
- [Lightning-fast Top Performance]: Fikwot FX991 M.2 SSD 500GB adopts NVMe protocol and PCIe Gen 4x4 specifications, and the maximum read and write speed can easily reach 6300MB/s and 3100MB/s.
