Manufacturer description

The Fikwot FN955 4TB packs PCIe Gen4x4 speeds into a single M.2 2280 stick, and the numbers are the reason to look: sequential reads up to 7300MB/s and writes up to 6300MB/s, backed by a dynamic SLC cache that absorbs large transfers before they hit the 3D NAND TLC underneath. That TLC choice matters if you plan to keep this drive for years — Fikwot rates its service life at 3x that of QLC flash, and the drive survived 80 hours of vibration and plug-cycle testing before shipping. At 4TB, this is the capacity tier that ends the delete-a-game-to-install-a-game cycle on PS5, and Fikwot builds…

SpecPicks Verdict

SpecPicks scored Fikwot FN955 4TB NVMe SSD M.2 2280 PCIe Gen4x4 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 FN955 4TB work in a PS5?

Yes. Fikwot markets the FN955 as PS5 memory expansion in the M.2 2280 PCIe Gen4x4 form factor Sony requires, and its 7300MB/s read speed clears Sony's 5500MB/s minimum. The listing does not mention an included heatsink, so plan to add one.

How fast is this SSD in real use?

Fikwot rates the FN955 at up to 7300MB/s sequential read and up to 6300MB/s sequential write over PCIe Gen4.0x4 with NVMe 1.4. Dynamic SLC cache sustains those peaks on large transfers; speeds drop once the cache fills, as with any TLC drive.

Is TLC flash better than QLC for a 4TB drive?

Fikwot uses original 3D NAND TLC and states it delivers roughly 3x the service life of QLC flash. For a 4TB drive holding a game library you rewrite often, that endurance gap is the main reason to pay for TLC.

What warranty comes with the FN955?

Fikwot includes a five-year quality warranty on the 4TB internal SSD plus round-the-clock technical support. Check the product listing for current registration requirements and regional terms before you buy.

Does it run hot enough to need extra cooling?

The FN955 pairs auto-adaptive temperature control with power efficiency management to reduce heat at the source, and it is rated for 0 to 60 degrees Celsius operation. A PS5 install still needs a heatsink per Sony's guidance.
