Customer Ratings & Reviews

The WD_BLACK SN850 NVMe SSD is an outstanding performer, delivering blazing-fast read and write speeds that significantly boost load times and overall system responsiveness. Its sleek design and excellent thermal management make it a top choice if your in the market for a new drive.

Drive is a decent size for future expansion. Solved my 1 TB woes of a couple games installed and the drive was 80% full. Drive speeds are fast and I've had no WD drives fail so far. I waited for a sale and for drive prices to come down. PCI gen 4 doesn't give up anything in performance.

WD SN850X drives are excellent performers. Sure, they won't get you the impressive speeds of NVME 5.0 drives. However, NVME 4.0 is still plenty fast. Based on real-world. Game load speeds are almost entirely unaffected by NVME 5.0 speeds over 4.0. Even file transfer, when the cache runs out, the speed plummets. This is my 5th WD SN drive after switching from Samsung 970 Pro and 970 EVO drives. This is my 2nd 4 TB drive, purchased to upgrade my 2nd PC 1 TB SN7100 drive. 4 TBs for under $270 was the sweet spot. CyberPunk 2077 now loads in 7.6 second oppose to 9 seconds on my old drive. So yeah, slightly noticeable speed improvement. With that said, this drive is worth the money. When installed, you will get about 3.64 GBs instead of 4 TBs of usable space.

Got this for my laptop specifically for video editing. Extremly reliable easy ti install. With a large drive you gaurentee speed where as an external will annaliate the system dude to the use of power it requires from the computor to boot an external drive.

You get a ton of space on this NVMe SSD hard drive. At the same time, it is very, very fast. We are using these over all the other popular brands from now on. Super impressed with the performance. The price is right as well. We highly recommend this hard drive.

I’ve been buying WD for a long time. Never once had issues. This 4 TB NVME is both fast, efficient and a decent value for today’s computers. It’s not a pci 5.0 offering blistering file moving capability, but most people don’t move data at those rates regularly, if it all anyway. Massive overkill in gaming at the moment as well. 5.0 units also generate more heat, and I think in another year or 2, the heat and prices will come down making them a better value. This will make them do what the 4.0 units like this one are doing today. Offering value and still, outstanding performance. The 8TB units are coming down in price but are a healthy chunk of money to purchase. There is more of the mid range market at 4TB, which more will gravitate to. Overall? Buy this if you want great storage and want to take up less motherboard nvme slots doing so. Additionally saving more money today, and down the road. 1000% recommend.

So it is fast like any good Gen 4 NVME drive. Nothing all that shocking there, but for the plsale price it is amazing. You will not beat it at 300. I use 0 sata drives in my computer so this is a life saver in terms of storage.

Luv it! Woks like a charm; no problems and easy setup.

Great NVME SSD. Read speeds are as advertised. Have had no issue with this drive at all. I've had it both my PS5 and my PC great drive for the price. Would definitely recommend. Can't beat the performance.

The SN850X is the perfect balance of quality, performance and price! Boot times are great and never had a single issue with drive recognition. Will continue to buy in the future!

Amazingly fast m.2. Upgraded from a 500gb drive to this for my game drive. Tons of space and fast

Used it to expand my storage even further. Price was great. It performs as expected. It is best to purchase a heatsink for it. Highly recommend it.

it was easy to install, fast, and reasonably priced. Additionally the store was quick with making it available for pickup

I used the drive to upgrade my storage in my original PS5 which seems to fill up storage quite quick. I had originally bought a 2tb version about a year ago but that didn’t last long and since i had absolutely no issues with the last WD-SN850, it was a no brainer to go with the same brand and not have to worry about firmware upgrades or the drive overheating while being used. Took a while to transfer all the games between an external drive and the new drive but was definitely worth it since I won’t have to worry about storage for at least anothet year.

These SSD are so reliable it is simply amazing. Extremely affordable, easy to use, and are true inexpensive to where we were even 4 or 5 years ago.

Building a new PC and needed some storage. This is fast and worked great.

Great performance and storage. I got it while it was on sale so the "per tb" price was low. I recommend getting a heatsink for it as they do tend to get hot during use.

I chose this over the Samsung 990 pro. I'm very happy with this decision. In terms of specs, these two products are very similar, but I have no complaints about the SN850x. PC startup is fast and I have a good amount of space. If you're debating whether or not you need 4 TB, do yourself a favor and get the 4 TB!

I used this in my M4 Mac Mini dock and it works amazing. No issues, it's blazing fast and was priced right.

This SSD has quick read/write speeds and easy to install.
