WD_Black SN850X 2TB NVMe PCIe 4.0 x4 M.2 Internal Gaming SSD

Our review of the WD_Black SN850X 2TB NVMe PCIe 4.0 x4 M.2 Internal Gaming SSD finds it best for gamers and power users who need large local storage and top-tier transfer speeds. The bottom line is simple: this drive delivers the speed and capacity expected from a modern PCIe 4.0 NVMe SSD, making it a practical upgrade for gaming consoles that accept M.2 drives and for desktops or laptops with an available M.2 slot. The single biggest reason to buy is the combination of roomy 2TB capacity with high sustained performance that customers specifically praise for gaming and system storage expansion.

Key Features

• PCIe 4.0 x4 interface: Enables faster sequential transfers than PCIe 3.0, reducing load times for large game installs and media files.
• 2TB capacity: Provides ample room for a large game library or to free up space on a system C drive without frequent housekeeping.
• M.2 2280 form factor: Fits most modern motherboards and compatible consoles that accept M.2 NVMe drives without adding bulk.
• No heatsink version: Gives flexibility to use the drive in systems where space or custom cooling solutions are required.
• Optimized for gaming: Designed to maintain performance during gaming sessions, which customers noted improved PS5 load behavior.

Who It's For

This SSD is ideal for PC gamers, console owners with M.2 NVMe expansion capability, and creative professionals who move large files and want faster app or project load times. If you maintain a large library of modern titles or media, the high capacity and PCIe 4.0 bandwidth make this a sensible primary or secondary drive.

It is less appropriate for users with older motherboards that only support PCIe 3.0 if they expect to fully utilize PCIe 4.0 speeds, and those who require an integrated heatsink should look for a heatsinked variant or add a compatible thermal solution, since this listing is without a heatsink.

Pros & Cons

Pros

• Excellent sustained speed under PCIe 4.0, noted by customers as improving console and PC load times.
• Large 2TB capacity gives breathing room for system and game storage without frequent deletions.
• M.2 form factor installs cleanly into compatible systems without taking extra bay space.

Cons

• Comes without a heatsink, so thermal management may be required in cramped systems or specific console installs.
• PCIe 4.0 benefits are limited on older systems that only support PCIe 3.0.

Specifications
