Welcome to Reviews inside tv, where we dive deep into the latest tech to help you make smarter choices. Today, we’re taking a close look at the WD_BLACK 4TB SN850X NVMe Internal Gaming SSD. This drive is built on PCIe Gen4 technology, offering read speeds up to 7,300 MB/s, designed primarily for gamers and performance-focused PC users. It comes in the M.2 2280 form factor and features Western Digital’s TLC 3D NAND flash memory, with capacities available up to 8TB. There’s also an optional heatsink version designed to help manage temperatures during heavy use.
Starting with the basics, the SN850X targets high-end gaming PCs and workstations that demand fast load times and reliable storage for large game libraries or intensive workloads. The heatsink variant aids in maintaining stable performance by dissipating heat, which can be critical for sustained gaming sessions. Additionally, WD’s Dashboard software provides monitoring tools for drive health, RGB customization on heatsink models, and a Game Mode 2.0 that optimizes system resources for gaming.
Setting up the SN850X was straightforward; installing the M.2 drive into a compatible motherboard slot took only a few minutes, and it was quickly recognized by the system. Using it as a primary storage for both games and applications, load times were noticeably reduced compared to SATA SSDs or older NVMe drives. Large open-world games launched swiftly, and file transfers consistently hit speeds close to the advertised 7,300 MB/s read peak in real-world benchmarks. The optional heatsink helped keep temperatures in check, preventing thermal throttling during extended gameplay or data-heavy tasks.
On the flip side, the drive does require a PCIe Gen4 compatible motherboard to fully realize its speed benefits; otherwise, performance will be capped by older PCIe Gen3 interfaces. The heatsink version, while beneficial for thermal management, adds some height to the drive, which might pose clearance issues in compact PC builds. The Dashboard software is Windows-only, so Mac users won’t benefit from those additional features. Also, while the SN850X is fast, it’s priced at a premium compared to some competitors that offer slightly lower speeds but come at a better cost.
Let’s talk pros: the build quality is solid, featuring Western Digital’s proven TLC NAND, ensuring good endurance and reliability. Performance is top-tier for PCIe Gen4 SSDs, making load times and file operations impressively quick. The optional heatsink effectively manages thermals, extending peak performance during heavy use. The customization and game-optimization features in the Dashboard software add an extra layer of control for users who want to tweak settings or monitor drive health.
On the downside, the premium pricing puts it out of reach for budget-conscious buyers. The height of the heatsink could cause compatibility issues in slim or compact builds. The lack of software support outside Windows limits the usability of advanced features for users on other platforms. Also, without a PCIe Gen4 slot, this SSD won’t perform to its full potential, so the hardware environment is a significant factor.
When considering value, the WD_BLACK SN850X 4TB model offers solid performance for its price, especially for gamers who need fast load times and ample storage space without compromise. The premium cost is justified by the combination of speed, capacity, and thermal management, but if you’re not running a Gen4 system or don’t prioritize peak speed, more affordable alternatives might fit your needs better.
Comparing it to other SSDs in this category, the SN850X stands out for its top read speeds and gaming-centric features like Game Mode 2.0. Some competitors might offer similar capacities at lower prices but often with slightly slower speeds or less sophisticated thermal solutions. The heatsink inclusion with all capacities is a thoughtful touch, giving it an edge in thermal performance compared to many rivals that sell heatsinks separately or not at all.
The build quality is robust, using high-grade materials typical of Western Digital’s SSDs, and the 3D TLC NAND contributes to solid endurance. Though long-term reliability data is limited due to the product’s relatively recent release, WD’s track record in storage gives confidence in durability.
While I didn’t need to contact customer support during testing, Western Digital has a solid reputation for responsive service, backed by warranties and support options that should reassure buyers.
For those looking for cheaper alternatives, drives like the Samsung 980 Pro or Crucial P5 Plus provide competitive PCIe Gen4 speeds at slightly lower price points but may lack some gaming-specific features and the optional heatsink, which helps in thermal performance.
To wrap up, the WD_BLACK 4TB SN850X NVMe SSD delivers on its promise of fast, reliable storage tailored for gaming and high-performance PCs. It’s especially suited for users with PCIe Gen4 motherboards who want quick load times, large capacity, and effective thermal management. However, its premium price and hardware requirements mean it’s not for everyone. If you want cutting-edge speed and can leverage the gaming features, this drive is worth considering.
