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.

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.

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.

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.

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.

Capacity: 4TB
Style: SN850X
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.

TL;DR This is an incredibly fast PCIe 4.0 SSD, no doubt about it. Performance is top-tier. However, the price is pretty steep compared to the competition, and the new "Game Mode 2.0" feature feels more like a marketing point than something that makes a real difference in my experience. Full Review: I decided to pick up the 1TB WD Black SN850X, partly because its predecessor, the SN850, was so popular. The high-end SSD space has gotten incredibly crowded, so I was curious to see if this new drive could really compete with some of the other major players. WD waited a while to release this, so my expectations were pretty high. The drive itself is single-sided, which is nice for compatibility and cooling in tight spaces. Technically, WD is using its 112-layer BiCS5 flash, which is a generation behind the 176-layer stuff from competitors like Micron and SK Hynix. But WD has a reputation for getting fantastic performance out of its hardware and firmware, and that seems to be the case here. They clearly know how to make the most of what they have. Performance is where this thing really shines. During my own file transfer tests, the write speeds were huge, holding over 6.4 GB/s for a very large cache of almost 250GB. After that cache fills up, the speed does drop to under 1 GB/s, which is expected. For gaming and general use, you're almost never going to notice that drop-off. It’s just blazing fast. My main point of skepticism is the "Game Mode 2.0" feature. The included Dashboard software is pretty good and lets you toggle this mode. It’s supposed to do fancy things like predictive loading and adaptive thermal management. Honestly, it's hard to tell if it's just a gimmick. The drive is already so fast that I couldn't perceive a real-world benefit from this mode being on. It feels a bit like a solution in search of a problem. So, while the performance is excellent, the price gives me pause. It's a hard sell when you compare it to other top drives that are often cheaper. The SN850X is an amazing performer, but you are definitely paying a premium for the WD Black name. It's a great drive if you can find it on sale, but at its full retail price, you might find better value elsewhere. --- For anyone interested, the exact product I purchased was listed as: WD_BLACK 8TB SN850X NVMe Internal Gaming Solid State Drive with Heatsink - Works with PlayStation 5, Gen4 PCIe, M.2 2280, Up to 7,200 MB/s - WDS800T2XHE The ASIN for the version I received was: B0B7CKVCCV

I purchased the WD Black SN850X 8TB NVMe SSD for my professional photography workflow, and it has exceeded all expectations. As a professional landscape photographer who works with large RAW files, I needed a high-capacity SSD with blazing-fast speeds, and this drive delivers on all fronts. Why I Chose This SSD: The 8TB capacity was crucial for managing my ever-growing library of photos, and the read and write speeds of up to 7,300 MB/s and 6,600 MB/s were exactly what I needed for seamless file transfers and efficient editing. I compared several options, and the SN850X stood out as the best balance of speed, capacity, and reliability. Installation Process: I installed this SSD using a Sabrent PCIe 5.0 NVMe adapter since my motherboard (ASUS ROG Strix X570-E) already had its M.2 slots filled. The installation was straightforward: 1. Inserted the SSD into the adapter. 2. Secured the adapter into a free PCIe slot on my motherboard. 3. Initialized the SSD in Windows Disk Management, and it was ready to use. Performance Results: I tested the drive using CrystalDiskMark, and the results were phenomenal (screenshot attached): Sequential Read: 7,246 MB/s Sequential Write: 6,669 MB/s These speeds exceed the manufacturer's claims, making it ideal for moving and editing massive files quickly. The WD Black SN850X is a game-changer for professionals. Whether you’re a photographer, video editor, or gamer, this SSD will enhance your productivity with its unmatched speed and reliability. Highly recommended for anyone needing top-tier performance and large storage capacity. Would definitely buy again!

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.
