5.0 out of 5 stars Blazing Fast and Runs Cool — Perfect for Gaming

I upgraded to the WD Black SN850X 1TB with Heatsink for my gaming pc after my ssd died, and it has exceeded every expectation. Installation was a breeze — it slotted perfectly into my motherboard's M.2 slot, and the built-in heatsink saved me the hassle of having to reuse the one i already had and made installing it easierThe speed is incredible. Boot times are almost instant, and games load fast AF. I’ve also noticed smoother performance although thats probably due to having a fresh windows install. The heatsink does a fantastic job — even under heavy load, temps stay well within safe limits.It’s also PlayStation 5 compatible, so this would be a great option if you're looking to expand your PS5 storage with something fast and reliable. although i dont own one so cant comment on anything about thatIf you want top-tier performance with excellent thermal control, this drive is worth every penny. Highly recommended!

Absolutely awesome drive, super-fast, super sturdy. Well worth the money.I upgraded my system from a 1TB WD_BLACK SN850 I'd managed to fill up.I was able to clone my installed 1TB System drive onto this new 2TB one in an enclosure without any issues, then just swapped the drives over and the PC booted right up and Windows didn't even seem to care it was running off a different drive.Faster and with more capacity, it's noticeably improved Windows performance. My old drive is now going to be used for the latest games (like Starfield) that require SSD's to run effectively... And of course, Skyrim will go on there... :)

5.0 out of 5 stars Reliable, fast and great brand.

Delivered promptly.I was actually looking for a 2tb and had one in basket already when I came across this WD Nvme.I decided to go for this over 2tb to give myself peace of mind.The installation is as easy as it can be. WD provided cloning software which after downloading it took about 4 minutes to clone my older Nvme and that's it really!It's fast and reliable brand. Downloaded WD dashboard from their website to use T.R.I.M and it works flawlessly.Overall happy with the quality and price point of this product.Haven't benchmarked it yet but this is next on my to do list over the weekend.-TM

Picked up the 4TB WD_BLACK SN850X for my gaming rig and it’s been awesome. Install was super easy, and right away I noticed how fast games load—seriously quick. Read and write speeds are as advertised, and everything just runs smoother overall.Tons of space too, so I don’t have to constantly delete stuff to make room. Temps have been stable, and performance hasn’t dipped at all even under heavy use.If you're into gaming or just want a beast of an SSD, this one’s solid. Definitely worth it.

4.0 out of 5 stars installed in ps5 had 1 issue which another reformat fixed. thanks

installed in my ps5 with no issues, does the job I did have some PS5 errors at first but i reformatted it again and has stopped. It may have been a small error upon first installation. but happy now and have had this for a fair few months now

5.0 out of 5 stars My go to NVME drives

I own many of the WD SN850x range, and found the read/write performance superb. Even on long sustained transfers this never skips a beat and just works fantastically well. Coupled with the speed performance, the reliability has been great also, touch wood I've had none fail on me.As an M.2 2280 NVMe SSD with PCIe Gen4 compatibility, you'd expect nothing less.As all NVME drives it is compact in size and I would highly recommend a heatsink on them to ensure no throttling happens due to overheating (not encountered but just a suggestion)

5.0 out of 5 stars Amazing SSD

Western Digital SN850X 4 TB (M.2) SSD

A.C. · 7 January 2024

One of the faster PCIe Gen4 x4 drives on the market.Note to self, always it's good to check motherboard specifications before getting a 2nd SSD. I got a bit surprised by the fact that the 2nd M.2 slot on the MB only supports half the speed of the M.2 slot next to the CPU, which means I could've just as well gotten a cheaper drive for that slot.
