    • Great quality and reliability
Capacity: 4TB Style: SN850X
Great quality and reliable functionality that you'd expect from Western Digital. The capacity is amazing, it has blazing fast read/write speeds, and installation was a breeze as it fits a standard M.2 socket. I was able to immediately initialize and partition it for use after installing it. This went into my laptop, so it obviously changed nothing externally and added only a few grams to the weight. It's pricey, but I'd rather get a good one from a brand I trust than just go with the cheapest option available. ... show more

    • Now a bit costly
Capacity: 4TB Style: SN850X
Excellent SSD. These are not as good as the Samsung IMO, but they are still fast and reliable. Just picked a new up on Amazon for $599. That hurts as I purchased one in Dec 2023 for $229! I do think these will just more expensive due t the memory demands right now. But if you need it, you need it. This one, again IMO, is the one to get as it has cache memory built into the SSD that helps move data along and does not rely on host memory to cache. Important if you use an external enclosure. The enclosures I use are OWC 1M2 in the Thunderbolt 4 and 5 interfaces. Not sure if the 5 interface is worth the $100 more. ... show more

    • Elevate Your Gaming Experience with Blazing-Fast Storage!
Capacity: 4TB Style: SN850X
Rating: ⭐⭐⭐⭐⭐ The WD_BLACK 4TB SN850X NVMe Internal Gaming SSD is a storage beast that revolutionizes your gaming and productivity experience with its astonishing speed and generous capacity. Pros: 1. Blistering Speed: The Gen4 PCIe interface and M.2 2280 form factor of this SSD offer speeds of up to 7,300 MB/s. This means lightning-fast loading times for games and near-instantaneous data access. 2. Massive Capacity: With 4TB of storage, you have ample space for your game library, multimedia, and work files. No more worrying about running out of storage or needing to juggle files. 3. Gaming Performance: The SSD is optimized for gaming, ensuring that your games load quickly and run smoothly, reducing lag and stuttering in resource-intensive titles. 4. WD_BLACK Dashboard: The WD_BLACK Dashboard software allows you to monitor your SSD’s performance and optimize it for your specific needs. 5. Reliable Brand: Western Digital is a trusted name in storage solutions, known for its quality and reliability. 6. M.2 Form Factor: The M.2 form factor allows for a clean and compact installation on compatible motherboards, saving space in your PC case. Cons: 1. Price: The combination of high capacity and Gen4 speeds comes at a premium. It might be overkill for users who don’t require the fastest storage or those on a tight budget. In summary, the WD_BLACK 4TB SN850X NVMe Internal Gaming SSD is a performance monster that transforms your gaming and storage experience. If you’re a gamer, content creator, or professional who demands the best in storage, this SSD is a top choice.

I’ve been using this drive for a few months, and it’s easily one of the fastest and most stable Gen4 SSDs I’ve tested. Benchmarks reached 7,133 MB/s read and 4,169 MB/s write in performance mode — right in line with WD’s specs. Even under load, it maintained around 6,500 MB/s read and 3,600 MB/s write, showing great consistency. For testing purposes, I also ran a power-saving “stress” scenario that intentionally limited performance to simulate extreme throttling. Those results were only for analysis — customers will never experience that kind of slowdown in normal use. Thermals stay solid with a basic heatsink (mid-50 °C), and there’s no throttling during long transfers. The WD Dashboard software is easy to use and adds an optional Gaming Mode for max speed. ⚖️ Pros: - Reaches full Gen4 performance (7,000+ MB/s reads) - Excellent sustained write speed and thermal stability - Rock-solid reliability for OS, games, or content creation - Intuitive WD Dashboard software ⚠️ Cons: - Can run warm without heatsink - Requires a PCIe Gen4 slot and good airflow for full speed 🏁 Final Thoughts: The WD_BLACK SN850X is a premium SSD that lives up to its reputation. Under the right conditions, it delivers near-theoretical Gen4 speeds and flawless stability. Even in multitasking or gaming scenarios, performance stays consistent and responsive. The “low” benchmark results included here were testing artifacts—stress conditions designed to show how power management affects throughput, not what normal users should expect. In everyday use, this drive is exceptionally fast, reliable, and built to last. ✅ Verdict: A flagship-level NVMe SSD that rewards systems tuned for performance. Highly recommended for gamers, developers, and creators who want speed with zero compromise. ... show more

    • Excellent SSD, Great Performance After Finding the Right Enclosure and Cable
Capacity: 8TB Style: SN850X
I bought the WD_BLACK 8TB SN850X NVMe SSD to use with the UGREEN 80Gbps M.2 NVMe SSD Enclosure and connected it to my M4 Max Mac Studio. At first, I noticed fast transfer speeds, but after transferring a few large files, the speed dropped significantly. Unplugging and reconnecting the enclosure temporarily fixed it, but the issue kept happening. I suspected the problem was the UGREEN enclosure since Western Digital drives have always been reliable for me. I returned the UGREEN and replaced it with the OWC Express 1M2 80Gb/s Enclosure. Transfer speeds were excellent, but the drive started disconnecting a couple of minutes after startup. The included USB-C cable was also too short. I replaced it with the OWC 0.8M Thunderbolt 5 (USB-C) Cable, and that completely solved the disconnection issue. Now everything works flawlessly, with consistent speeds of around 5800 MB/s write and 5600 MB/s read, and the enclosure stays cool during long transfers. It took some troubleshooting, but I’m very satisfied with the final setup. ... show more

    • Very fast but a little hard to put together.
Capacity: 4TB Style: SN850X
Let me preface this by saying I am in no means an expert in the computer building industry so I had no idea what I was doing. The most I have ever done was install a new gpu and power supply and I had to use youtube EXTENSIVELY to do so. Now with that out of the way lets get into the SSD. I compared this to the WD BLACK external hard drive that I had prior and the speeds could not be more night and day. The SSD was MUCH faster and made games seamless in loading times. I loved it so much I got 2, one for me and one for my wife. I did get these on sale for around 300 compared to the 700 I had seen prior at that time. I would definitely recommend this to anyone who wants a LOT more speed. This helped with downloading games and verifying files. Now with the great parts out of the way, the only issue that I had with this was setting it up. I did not know you had to format the space, it was not just plug and play which is unfortunate but I was misguided. It does not say this in the instructions so I was unaware. Hopefully anyone having the same issue reads this and it helps. I would 200% say it was worth the money and honestly I'd probably buy another if money allowed. ... show more
