3. Performance Analysis

Performance is the key factor for most users when selecting an SSD, and the WD Black SN850X does not disappoint. This section will analyze the sequential and random performance metrics, as well as real-world testing scenarios.

Sequential Read and Write Performance

The SN850X boasts a sequential read speed of up to 7300MB/s and a sequential write speed of up to 6300MB/s. These figures place the SN850X among the fastest SSDs available on the market, particularly in the consumer space. This level of speed is particularly beneficial for tasks such as:

  • Loading large game files: Significantly reduces load times in open-world games.
  • Handling 4K/8K video editing: Allows for smoother playback and editing of high-resolution video files.
  • Operating system boot times: Provides near-instantaneous boot times, enhancing the overall responsiveness of the system.

In benchmark tests, the SN850X consistently delivers on its promised speeds, often exceeding the advertised figures under optimal conditions. This makes it an excellent choice for users who require maximum throughput for their applications.

Random Read and Write Performance

Random read and write speeds are critical for overall system responsiveness, particularly in scenarios involving small file operations, such as launching applications or handling multitasking environments. The WD Black SN850X delivers 800K IOPS (input/output operations per second) for random reads and 1100K IOPS for random writes.

These impressive IOPS ratings ensure that the SN850X can handle intensive multitasking with ease, making it ideal for:

  • Gaming: Smooth gameplay with minimal texture pop-ins or lag.
  • Content creation: Efficiently managing large numbers of small files in software like Adobe Photoshop or Premiere Pro.
  • General system usage: Quick access to frequently used files and programs, even when the system is under heavy load.

4. Gaming Performance and Features

The WD Black SN850X is marketed as a gaming SSD, and it’s equipped with several features that make it stand out in this category.

Game Mode 2.0

One of the standout features of the SN850X is the inclusion of Game Mode 2.0, accessible via the WD_BLACK Dashboard. This mode is specifically designed to optimize the SSD’s performance during gaming sessions. When activated, Game Mode 2.0:

  • Reduces latency: Minimizes the time it takes for the drive to respond to data requests, crucial for fast-paced gaming.
  • Improves texture loading: Ensures that textures load quickly and seamlessly, reducing the chances of encountering pop-ins.
  • Enhances overall system performance: Allocates more resources to the game, potentially boosting frame rates and reducing stuttering.

During testing, enabling Game Mode 2.0 resulted in noticeable improvements in load times and overall gameplay smoothness, particularly in demanding titles such as “Cyberpunk 2077” and “Red Dead Redemption 2.”

Compatibility with PlayStation 5

For console gamers, the WD Black SN850X also offers compatibility with the PlayStation 5, though it’s worth noting that only the heatsink version is officially supported. The SSD meets the stringent requirements set by Sony for use with the PS5, including the need for high sequential read speeds and adequate thermal management.

Installing the SN850X in a PS5 is straightforward, and once installed, it performs admirably, with game load times and installation speeds comparable to, or even better than, the PS5’s internal SSD. This makes it a strong option for gamers looking to expand their console’s storage without sacrificing performance.

5. Thermal Management and Heatsink Option

Thermal management is a critical aspect of SSD performance, especially in high-performance models like the SN850X. Excessive heat can lead to throttling, where the SSD reduces its speed to prevent overheating, which in turn can negatively impact performance.

Heatsink Option

The SN850X is available with an optional heatsink, which not only adds to the aesthetic appeal of the SSD but also plays a crucial role in maintaining optimal temperatures during intense workloads. The heatsink is designed to dissipate heat effectively, ensuring that the drive operates at peak performance even during prolonged gaming sessions or heavy data transfers.

In testing, the heatsink version of the SN850X showed significantly better thermal performance compared to the non-heatsink version. Under sustained loads, the drive’s temperatures remained within safe limits, and there was no evidence of thermal throttling, which can be a concern with high-speed NVMe drives.

Adaptive Thermal Management

In addition to the physical heatsink, the SN850X also features Adaptive Thermal Management technology. This system dynamically adjusts the drive’s performance based on temperature readings, ensuring that it remains cool without compromising too much on speed. This feature is particularly beneficial for users who opt for the non-heatsink version or who are operating the drive in a less ventilated environment.

6. Endurance and Reliability

When investing in an SSD, endurance and reliability are key factors to consider, especially for users who plan to use the drive for intensive tasks over a long period.

Endurance Rating (TBW)

The WD Black SN850X comes with an endurance rating of 600 TBW (terabytes written) for the 1TB model. This means that the drive can handle writing up to 600 terabytes of data before it is likely to start showing signs of wear. For most users, this represents several years of usage, even under heavy workloads.

  • Everyday users: Likely to never reach the TBW limit within the warranty period.
  • Power users: Even with regular large file transfers, video editing, and gaming, the endurance rating ensures the drive will last several years.

Reliability and Warranty

Western Digital backs the SN850X with a 5-year limited warranty, providing users with peace of mind regarding their investment. Additionally, the drive undergoes rigorous testing and certification processes to meet various international standards, including CE, FCC, and UL certifications.

In terms of reliability, the SN850X has shown excellent results in stress tests, with no significant degradation in performance over time. The combination of high endurance and robust thermal management makes it a dependable choice for long-term use.

7. WD_BLACK Dashboard Software

The WD_BLACK Dashboard is a versatile utility that comes with the SN850X, offering users a range of features to monitor and optimize their SSD’s performance.

Features of WD_BLACK Dashboard

  • Drive Health Monitoring: Provides real-time data on the drive’s temperature, capacity, and overall health, helping users to keep their SSD in optimal condition.
  • Game Mode 2.0 Activation: As discussed earlier, Game Mode 2.0 can be toggled on and off via the Dashboard, allowing users to optimize their SSD for gaming.
  • Firmware Updates: Ensures that the drive is always running the latest firmware, which can improve performance and stability.
  • RGB Lighting Control: For those who opt for the heatsink version with RGB lighting, the Dashboard allows for customization of the lighting effects, enabling users to sync it with their other RGB components.

The WD_BLACK Dashboard is user-friendly and provides a comprehensive set of tools that enhance the overall user experience. However, it’s important to note that the software is only available for Windows users, which may be a limitation for those using other operating systems.
