Customer Ratings & Reviews

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!

This is such a good deal, I bought 2. They are now in my server and are connected in a RAID-Z Mirrored configuration. Highly recommended.

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

Works wonders and gives me all the space i need for my games.

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.

This is the best internal SSD I have ever come across in my entire 15 years of building custom pc's. I would recommend this SSD to anyone that really needs the space and the fast response time with the SSD. This current SSD is in my computer and it is the fastest, and best SSD that I have used so far as long as storage goes.

The Enthusiast's Champion. The WD Black SN850X 4TB is an uncompromising powerhouse. It is the definitive choice for the user who demands the very best PCIe 4.0 experience without exception.

The drive was easy to install and set up. It replaced the system drive in a laptop, and the cloning software had no issues recognizing the drive. The drive is fast and has lots of storage space. It's a little on the expensive side, but pretty much any drive this big is going to be a bit on the expensive side. Definitely worth the money.

Fantastic performance with maximum storage. I used this to replace my 2TB in PS5, and now I have double the storage, with increased performance faster than my old SSD. I didn't get a heatsink as I don't game that hard, but I highly recommend it if you do.

Installs easy fast and large enough for all my games.

Not only are the speeds of this drive insane but at 4TB of storage it also feels like you always have space for more games. Also considering it's meant to be a $520 Firecuda 530 competitor it comes in at a decent price point for what it is.

Working great. Don’t know what else to say, either these work or they don’t, and this one is working fine.

Its great. Super fast. Eqsy install. I wouldnt go backnto a regular SSD after this. Youll be the first to load thebmap, but you still gotta wait on the slowest player in the game. Hahahahahahahahahahagahagahahahahagagagagagagagagagahahahahafafafafajahahaahahahahahahagagayatatatatatatatatat farts

Amazing! Got it for my ps5 and it was easy to install. I had to buy a heatsink separately but saved more money that way than purchasing the one marketed for the PS5. Highly recommended simply to make sure all your favorite games are ready to go whenever you wish.

I'm using it on my Asus Rog Strix G18 as a main ssd. Loads fast and plenty of storage for my games and files

Perfect out if the box, this allowed me to perfect my gaming setup

so fast, put in my PlayStation 5 slim so I'm able to download my entire library

Works great. Just what I was looking for, for my PS5.

I did weeks of research and decided to go with it, so far it is awesome!! got a great deal from best buy too.

Western Digital does it again with this product, it is truly a phenomenal device that works perfectly. This product is easy to install, comes with good support software from Western Digital's website, and it is quite speedy.
