FN955 2TB NVMe SSD M.2 2280 PCIe Gen4x4 - High-Speed Storage

In this review of the FN955 2TB NVMe SSD the bottom line is simple: this drive is aimed at users who need very fast, high-capacity internal storage for gaming, content work, or system upgrades, and the main reason to buy is its sustained Gen4 performance that cuts load and transfer times dramatically. Installation is straightforward for compatible systems, the drive uses modern NVMe 1.4 and PCIe Gen4x4 lanes, and the dynamic SLC cache and 3D NAND TLC combine to deliver read speeds up to 7300MB/s and reliable endurance for everyday and heavier workloads.

Key Features

• Up to 7300MB/s read: Offers dramatically reduced game load and file transfer times compared with SATA drives, speeding workflows and play sessions.
• Up to 6300MB/s write: Fast sustained writes help when moving large media files or installing and updating games and software.
• 3D NAND TLC flash: Uses TLC flash that is rated for longer service life than QLC, improving real-world durability under sustained use.
• Dynamic SLC cache: Automatically configures cache to accelerate small writes and burst transfers for snappy desktop performance.
• Auto temperature control: Built-in thermal and power management reduce heat generation and help maintain consistent performance under load.
• Wide compatibility: Works in desktops and many laptops and supports Windows 8/10/11, making it a flexible upgrade option.

Who It's For

The FN955 2TB NVMe SSD is best for PC builders, gamers with Gen4-capable motherboards or consoles that accept M.2 drives, and content creators who need both large capacity and high sequential speeds for media transfers. It suits anyone replacing slower SATA drives or smaller NVMe drives to gain noticeable responsiveness when loading projects or games.

Users with older systems limited to PCIe Gen3 will still see an improvement over SATA, but will not reach the top speeds; those seeking the absolute quietest or passively cooled options should check physical cooling and case space, and users who need guaranteed compatibility with a specific laptop model should verify motherboard support first.

Pros & Cons

Pros

• Very high sequential read and write throughput for faster load and transfer times.
• Large 2TB capacity provides ample space for games, applications, and media libraries.
• 3D NAND TLC and SLC cache deliver better endurance and responsive burst performance.
• Automatic temperature and power management help keep the drive stable under sustained use.

Cons

• Compatibility is mixed on some platforms, so a system BIOS or slot limitation may prevent recognition in a few machines.
• The drive can require active cooling in tightly packed systems to maintain peak Gen4 speeds over long transfers.

Frequently Asked Questions

Will this drive work in my laptop?
The drive fits M.2 2280 slots and supports standard NVMe; make sure your laptop has a PCIe Gen4 or Gen3 M.2 slot and that the BIOS supports NVMe drives.

Does it need a heatsink to run at full speed?
Some compact systems may benefit from active cooling or a heatsink to sustain peak Gen4 speeds during long transfers, while many desktops with good airflow will be fine without one.

What operating systems are supported?
The manufacturer lists compatibility with Windows 8, 10 and 11, and it will work with other OSes that support NVMe drives though drivers/firmware checks are recommended.
