FN960 4TB M.2 PCIe Gen4 x4 NVMe Internal SSD - Fast PS5 Upgrade

In this review the FN960 4TB M.2 NVMe drive stands out as a high-capacity, high-speed internal SSD aimed at gamers and power users who need both storage and sustained performance. The single biggest reason to buy is its blend of near-Gen4 peak transfer rates and a built-in heatsink option that makes it a practical PS5 expansion or desktop upgrade without immediate thermal throttling concerns. The review covers real-world use, compatibility notes, and the balance between speed, capacity, and warranty support.

Key Features

• M.2 PCIe Gen4 x4: Delivers up to 4,800MB/s read and 4,200MB/s write speeds for fast load times and file transfers on supported systems.
• NVMe 1.4 compatible: Modern protocol support helps with efficiency and sustained throughput in demanding tasks like large file transfers and game installs.
• Dynamic SLC cache: Helps maintain peak performance during bursts and mixed workloads by reducing write amplification.
• Aluminum heatsink and pad: The included high-conductivity pad and heatsink improve temperature regulation to reduce the chance of thermal slowdowns during long sessions.
• Wide compatibility: Works in desktops, laptops and is sized and designed to be installed in a PS5 with the heatsink attached for expanded console storage.
• Durability and warranty: Rated up to 2,800TBW and backed by a five-year product registration warranty with 24-hour technical support.

Who It's For

This drive is best for PS5 owners who want to expand console storage with a name-brand compatible M.2 solution and for desktop users who need a large 4TB Gen4 NVMe for game libraries, video editing scratch disks, or fast project storage. The heatsink and dynamic SLC cache make it a sensible choice for sustained transfers.

Users who only need small incremental storage, or who lack a Gen4-capable slot, should look at lower-capacity or Gen3 options to save cost. Those requiring enterprise-grade endurance beyond the stated TBW or specialized data-center features should consider drives targeted at that market.

Pros & Cons

Pros

• Very fast sequential read/write performance for a Gen4 consumer drive, improving load times and transfer speeds.
• Large 4TB capacity provides room for extensive game libraries and multimedia projects without frequent juggling.
• Comes with an aluminum heatsink and thermal pad to better control temperatures under load.
• Solid warranty and a high TBW rating that add confidence for long-term use.

Cons

• Some customers find the heatsink size mixed in fit; it may be bulky in tight laptop bays or certain enclosures.
• One reported compatibility issue where a console entered safe mode, so always check console firmware and installation steps before use.
