It can be used for:

• AAA games
• Competitive games
• Windows
• Applications
• Game launchers
• Photos
• Videos
• Creative projects
• Documents
• Frequently accessed files

Actual usable formatted capacity will be lower than the advertised 1TB.

PCIe Gen4 x4

The SN850X uses a high-performance PCIe 4.0 x4 interface.

Compared with PCIe Gen3 NVMe drives, PCIe Gen4 provides substantially more available bandwidth, allowing the SN850X to achieve read speeds exceeding 7 GB/s.

Interface

• PCIe Generation: PCIe Gen4
• Lanes: x4
• Storage Protocol: NVMe
• Form Factor: M.2 2280

A compatible PCIe Gen4 M.2 slot is required to achieve the drive's maximum performance.

M.2 2280 Form Factor

The WD_BLACK SN850X uses the standard M.2 2280 form factor.

• Width: 22mm
• Length: 80mm
• Form Factor: M.2 2280
• Installation: Internal

The compact M.2 design connects directly to a compatible motherboard or laptop without SATA power or data cables.

Built for Gaming

The SN850X is part of WD_BLACK's gaming-focused storage lineup.

Its high-performance design can help provide:

• Faster game loading
• Faster level loading
• Faster installation and updates
• Reduced storage-related waiting
• Faster large-game file transfers
• Responsive multitasking

It is particularly well suited to modern games with large textures, maps, and installation sizes.

Microsoft DirectStorage Support

The WD_BLACK SN850X supports Microsoft DirectStorage on compatible systems.

DirectStorage is designed to improve how supported games access data from high-speed NVMe storage, potentially allowing:

• Faster asset loading
• Reduced CPU storage overhead
• Faster loading of game environments
• Better utilization of NVMe SSD performance

Benefits depend on the game, Windows version, GPU, and overall system configuration.

WD_BLACK Dashboard

Windows users can manage and monitor the SN850X through the WD_BLACK Dashboard software.

The software can provide features such as:

• SSD health monitoring
• Available capacity information
• Temperature monitoring
• Performance information
• Firmware updates
• Gaming optimization settings
• Game Mode 2.0

Game Mode 2.0

The SN850X supports Game Mode 2.0 through WD_BLACK Dashboard on compatible Windows systems.

Game Mode 2.0 includes gaming-focused optimization technologies such as:

• Predictive Loading
• Overhead Balancing
• Adaptive Thermal Management

These features are designed to optimize SSD behavior during gaming workloads.

Thermal Management

High-performance PCIe Gen4 SSDs can generate significant heat during demanding workloads.

The SN850X incorporates thermal-management features designed to maintain reliable performance.

For desktop gaming PCs, good system airflow and an appropriate motherboard M.2 heatsink can help maintain performance during sustained workloads.

No Heatsink Version

The WDS100T2X0E is the standard 1TB SN850X version without an integrated heatsink.

Heatsink

• Built-in Heatsink: No
• Compatible motherboard M.2 heatsink: Recommended where appropriate
• Suitable for systems with existing M.2 cooling solutions

This distinction is important because WD also offers SN850X variants with factory-installed heatsinks.

Endurance

The 1TB SN850X is rated for up to 600 TBW (Terabytes Written).

Reliability

• Endurance: 600 TBW
• Warranty: 5-Year Limited Warranty

This makes it suitable for demanding everyday gaming and high-performance PC workloads.
