Customer Ratings & Reviews

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.

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

Coming from a long time "Only Samsung SSDs" purchaser, I actually own several of these now and recommend these over Samsung for most applications. Too bad the prices skyrocketed in 2026 :-(

Necessary to build your computer, I’m glad I was able to grab this quality product at Best Buy

It's very reliable and useful, super easy to install too. This is my second one, and I am very satisfied.

Great storage capacity and speed even in a secondary slot. I might need to get another one soon already.

The speed difference with the WD_BLACK SN850X was noticeable right off the bat! It’s been a night-and-day difference in performance and thermal control. Even while running heavy programs like Revit and Rhino, the temperature stays around 45°C. It’s worth noting that my laptop only supports PCIe Gen 3, so that might be why it stays so cool, but it's still incredibly fast. I also really like the SanDisk Dashboard monitoring software which gives you the temperature of the drive in real time. I definitely recommend the 4TB version for architecture students who need the extra breathing room and reliability.

SSD SD SN850X very fast Reliable and Has a huge option for storage. 4TB, on a single stick. Truly stands all Out

Got the advertised speed even in my laptop. Just added a thermal pad and it's flying in the ROG flow x16. Perfect size for a game drive. During gaming it only gets to the low 50s in temperature and that's in a hot laptop. This is my 3rd drive. I have another one waiting to go on my gaming PC and one already in my PS5. These drives are great and when they go on sale they're totally worth the cost. To think, a year ago they were double in price.

Easy install, it's fast and price wasnt half bad. It's an SSD and it does everything you'd hope and SSD would do

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 purchased this to Upgrade my PS5, the installation was super easy, and it works just as it should. If you plan on putting this in the Playstation I would highly recommend picking up some type of Heatsink that's recommended for the PS5. I used the Sabrent and it all fit like a charm.

Easy to install, operating well. Using it for a dedicated gaming drive: load times are fast, and performance has been great.

I love this card. It is the third one that I have in my computer. Copying or moving files to Or from These cards is extremely fast. I can't praise them enough. Recommend to everyone Who can afford them. I bought this one During the Black Friday sale. Wish I had bought two Because now They're backup to 299. 99. But this is still A good bargain Especially for The speed And the TBW.

I replaced a 2tb samsung 980 pro that was getting low on space. I also never was thrilled with the performance. Based on reviews i gave this drive a go. The space is perfect and most important my pc feels like a different machine. Load times are blazing fast. I couldn’t be happier with this purchase.

Had a very good price point, fast, and very easy to install.

i have always liked WD SSDs. and this one is no exception. great speeds and great price point for the performance.

Not much to say here. This m.2 is fast and doesn't get too warm. I installed a Sabrent(sp?) heatsink, not that it really needed it, and its been blazing data since install. Speeds are exactly as stated by WD and can be counted on.

I was running a few SATA Samsung SSDs and even a very nice nvme EVO970+, but after getting a taste of the SN850X there was no stopping it. Great performance at an amazing price. I can't wait to see WD and Samsung come out with, the consumer is glad to see a competitive market!
