Customer Ratings & Reviews

Works great with my PS5. Highly recommend for anyone who needs a lot of extra storage.

The laptop is so much more useful having the extra memory. We have a lot of files that we keep on the computer and this extra memory really helps.

So fast easy, transferring things in my laptop is ridiculous. I couldn't imagine transfering between 2 of these.

Not the best but has a good price to pwrformance in the Gen 4 space.

However, does not come with a screw or protective cover. Sold separate.

I wish these were sold in a bundle with a PS5. They also transfer a ton of data in a small amount of time.

Was able to put a heat sink on and toss it in my PS5 and it worked like a charm

OP AF. One of the best NVMe drives you can get at the 4tb capacity.

The upgrade I needed for my system as my it was running slower and slower.

Fast shipping great value for ssd of it size very helpful with matching a heat sink for the product

Was able to price match with microcenter which was gladly unexpected

dont order from here they hornor there develiver dates and they need to do better and give people discount for it

Installed in PS5, no issues whatsoever and great speeds.

I recently purchased the WD - BLACK SN850X 4TB Internal SSD, excited about the potential boost in storage and performance for my system. Unfortunately, my experience has been deeply disappointing due to the SSD being defective. Despite extensive troubleshooting, including updating my motherboard's BIOS, checking and rechecking physical connections, and trying different SSD slots, the drive was never recognized by my system. I even consulted various technical resources to ensure I wasn't missing any steps in the installation process. My motherboard, an ASRock Z690-C/D5, is fully compatible with NVMe PCIe Gen 4 x4 SSDs, so compatibility should not have been an issue. The situation was frustrating, especially considering the premium price point of this product. An SSD of this caliber and cost should work seamlessly, or at the very least, have reliable customer support to assist when issues arise. Unfortunately, this was not the case. I had high expectations for this WD - BLACK SN850X SSD, given the reputation of Western Digital and the advertised capabilities of the product. It's disheartening to encounter such a critical issue right out of the box. I hope this review serves as a cautionary tale for others considering this SSD. It's imperative for high-end components like this to undergo rigorous quality checks before reaching consumers.

Its A great m.2 It works Great buy it. I recommended it

Works great in my laptop. Running out of space for games.

Easy to install and format. The only reason for the 4 star is the price.

This has been a really odd experience for me. I bought this to install in my gaming laptop and it ended up only being detected between 10-20% of the time. It may be an issue with the laptop, but after reinstalling it multiple times, there was no difference. I’ve tried others and they functioned properly. The only saving factor was I was able to switch the one I had in my ps5 and it seems to work appropriately in there. Very odd. It is possible it’s a Western Digital issue? It ended up working out in the end, so I guess that’s a good thing…

Only had like 3.6 TB on it. I know you dont get a full 4tb regardless of what brand you go with, but seriously, why advertise it as a 4tb drive if is missing almost 500gb of storage?

Fastest drive on the market for Gen 4 PCIe. WD wins again.
