Product information

Description

The WD_BLACK SN850X NVMe SSD is a high-performance PCIe Gen4 storage drive designed for gaming and demanding applications. Available in capacities from 1TB to 4TB and with an optional heatsink on 1TB and 2TB models, this SSD offers very high sequential speeds and low latency to reduce load times, stuttering and in-game asset pop-in.

Advantages

Extreme read/write performance up to 7,300 MB/s delivers much shorter load times. Low latency improves responsiveness and reduces stutter during gameplay. Larger capacities let you store multiple modern AAA titles without frequent uninstalling. The optional heatsink for selected capacities helps sustain peak performance under extended heavy use. Game Mode 2.0 (Windows only) adds features such as load prediction to optimize in-game asset readiness.

Key specifications

  • Form factor: M.2 NVMe
  • Interface: PCIe Gen4 x4
  • Sequential read speed: up to 7,300 MB/s
  • Capacities: 1TB, 2TB, 4TB
  • Optional heatsink available for 1TB and 2TB models
  • Game Mode 2.0 support (Windows only)

How to use

Install the SN850X into an M.2 PCIe Gen4 slot on a compatible motherboard, secure it with the mounting screw, and ensure the system BIOS recognizes the drive. For models with an optional heatsink, fit the heatsink according to the manufacturer instructions before installation if required. Install the operating system or format the drive in OS disk management tools, then install games and applications to the SSD to benefit from reduced load times and improved responsiveness. Enable Game Mode 2.0 in WD software on Windows systems to use load prediction and other performance features.

Recommendations

Use the WD_BLACK SN850X in a PCIe Gen4-capable M.2 slot for best performance, keep firmware and WD management software up to date, and consider the heatsink option for sustained peak speeds during long gaming sessions.
