Pros & Cons

Pros

  • ✓ 7100MB/s read / 5300MB/s write on PCIe Gen 4x4
  • ✓ 2280 form factor fits PS5 expansion bay, laptops and desktops
  • ✓ Graphite heatsink holds reads near peak under sustained load
  • ✓ 5-year limited service backed by a 1200TBW endurance rating

Cons

  • ✗ 3D QLC NAND writes slower than TLC once SLC cache fills
  • ✗ DRAM-less design leans on host HMB, so speeds vary by system
  • ✗ 1200TBW is modest for 2TB if you write heavily every day
  • ✗ Fikwot is a lesser-known brand with a shorter support track record

Manufacturer description

The Fikwot FX991 is a 2TB M.2 2280 NVMe drive built on PCIe Gen 4x4, and it targets the sweet spot between console expansion and desktop boot duty. Sequential reads reach up to 7100MB/s with writes up to 5300MB/s, which puts it in the same speed bracket as the Gen 4 drives Sony recommends for PS5 storage expansion. Fikwot pairs 3D QLC NAND with Host Memory Buffer (HMB) and a dynamic SLC cache, so the drive borrows system DRAM instead of carrying its own — a design that keeps startup, multitasking, and game asset loading fast without adding cost. Thermals are handled by a high-conductivity…

SpecPicks Verdict

SpecPicks scored Fikwot FX991 M.2 SSD 2TB 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. It is an M.2 2280 PCIe Gen 4x4 drive that Fikwot lists as compatible with PS5 storage expansion, and its 7100MB/s read speed clears the Gen 4 bar Sony expects.

How fast is the Fikwot FX991 2TB?

Fikwot rates it at up to 7100MB/s sequential read and up to 5300MB/s sequential write over PCIe Gen 4x4. Real-world speeds depend on your motherboard slot and workload.

Does it come with a heatsink?

It ships with a high-conductivity graphite heatsink. Fikwot says read speeds stay close to peak under high load, though PS5 owners should confirm bay clearance before installing.

What warranty does the FX991 include?

Fikwot provides a limited service of up to 5 years or 1200TBW, whichever comes first. Check the product listing for current terms in your region.

Is QLC NAND a problem for gaming?

For game loading, mostly reads, QLC is fine, and HMB plus SLC caching keeps everyday transfers quick. Long sustained writes past the cache will slow more than on a TLC drive.
