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. Read more

The 1TB WD_BLACK SN850X was one of the best upgrades I made to my PC. Installation in M.2 format was quick and easy, and I noticed the difference from the very first boot: game loading times were drastically reduced, and the system responded with impressive smoothness. Speeds of up to 7,300 MB/s are truly noticeable in every large file transfer. Furthermore, the compact and elegant design fits perfectly in my system. Without a doubt, this is an SSD designed for gamers seeking power and stability. Read more

I’ve been using the WD_BLACK SN850X 2TB NVMe SSD as my main drive and it’s been excellent. Installation was easy, and the speed difference was noticeable right away — fast boot times, quick game loads, and smooth performance overall. Thermals have stayed under control with normal airflow, and the 2TB capacity is perfect for a modern PC setup. No issues so far. Great choice if you want fast, reliable Gen 4 NVMe storage. Read more

Western Digital is a strong contender in the world of storage amongst other big names such as Samsung and the like. WD Pros - 1TB is enough to save a ton of data -Zero compatibility or connectivity issues - NVMe is fast, and easy to install Cons -Wish it was cheaper WD scratches the itch for a fast NVMe SSD for my storage needs, maybe yours too.

I picked up the 4TB SN850x. It arrived from Amazon the same day. I replaced a Samsung 1TB 980 that was nearly full. I pre-loaded the WD Acronis & Dashboard software (that you can download from their website). I placed this drive in the 2nd NVMe slot on my mother board. I formatted the drive and then started Acronis. The migrations was easy, just make sure you read carefully so don't migrate the wrong drive and erase everything. I was amazed how quickly it migrated nearly 1TB of data, it took less than 10 minutes. I shut down the PC, removed the old drive, placed the new SN850X in the old drives slot and was back in action. My Intel ethernet port stopped functioning, but I am not 100% sure it was related. I had to disable it in the BIOS, restart the machine, enable it again and then it worked. Only mentioning it in case it happens to you. Anyhow, the who process was quick and relatively simple. The drive claims it can read at 7,300MB Per Second and I am calling BS on it. I ran a benchmark several times and at best pulled 6,800MB Per Second. That is my only complaint. My machine is high end, a fast CPU a ton of RAM and had nothing else running. I had everything under the dashboard enabled, googled how to optimize it...... There is a chance that perhaps I did something wrong, but I do not think that is the case and if I have to do 4 hours of research to figure it out, that is on them for making it too complicated. Aside from that, the drive is awesome and a great deal for the capacity and performance you get from it. I would purchase it again. Samsung's software is a little better in my opinion, but perhaps that will improve in time. Read more
