I usually stick with Crucial for most of my storage needs, including my P3 and T500, but I needed a 4TB NVMe drive to store more games, and Crucial didn’t have any available that were reasonably priced or in stock.I’ve used Western Digital before, but only for HDDs. However, I have to say, this is one of the BEST SSDs I’ve ever used.With 4TB of space and blazing fast speeds, it’s impressive. My Crucial T500 is rated for similar speeds but doesn't consistently reach them. Typically, my T500 maxes out around 6800MB/s, while this Western Digital drive can hit up to 7400MB/s.

I purchased this drive direct from Western Digital and it didn't last a year. I'm now currently using a different NVMe drive now and my PC is working fine. I had this SN850X setup as a boot drive with Windows 10 desktop and I kept the PC up to date (drivers included). I always go through the standard shutdown process every time and one day it just couldn't boot to Windows. The drive no longer showed up in BIOS and using a external enclosure with the drive in it was unrecognizable. I contacted WD customer service and went through troubleshooting with them and came to the conclusion that the drive was dead (most likely firmware corruption). The drive was under warranty but they wanted it sent back to them with no physical damage. I'm not comfortable sending my drive ...

My second computer build is a ROG STRIX Z790-H WiFi with an i7-14700K and DDR 5 7200MHz memory. That specification needs PCIe 4 memory in the boot drive to match. I've used WD SN850 before, but not the updated X version. The Z790-H has heat sinks on all the PCI-e memory slots, so the SN850X didn't require an integral heat sink. Although this is an air cooled system - Noctua NH-D15 - the system runs happily at 7200MHz on XMP2 profile, with almost instant boot up. The bonus is WD has a free download of ACRONIS True Image backup software with a five-year licence, in addition to the memory administration app.I've titled this "SCAN saves the day".

On the Saturday afternoon, an email advised that the memory was lost, and the website showed it would be 3 or 4 weeks before they had a consignment. I ordered the memory from SCAN for the same price, with a silent thank you that it would be delivered the following week. It was delivered the following day - Sunday - so I could complete the build and start the first run. Great job SCAN and thank you!I recommend the WD Black SN850X, but the important thing is I recommend SCAN who are likely to become my default computer components retailer.

I was upgrading my MSI Laptop GE66 Raider over the fall. I started by upgrading my RAM from 32 to 64 GB. My next step is to upgrade both my SSD for faster performance. The WD SN850 is worth the price now that it is a bit cheaper. It was also a major upgrade from the previous WD Black which was a 750 that came with my laptop. I highly recommend it for those who are looking to boost their performance.Also for those who are relativity new and becoming more of a D.I.Y. AKA F around and find out. Make sure that you back up everything back up and have a reinstall of Windows, not sure about Linux but I believe it's the same process. I went to reinstall to new SSD and everything went well. I turn on the Laptop and it went to BIOS. I went on my phone and Lookup what the ... MoreI was upgrading my MSI Laptop GE66 Raider over the fall. I started by upgrading my RAM from 32 to 64 GB.

I turn on the Laptop and it went to BIOS. I went on my phone and Lookup what the issue is. I just need to reinstall Windows. Again you gonna learn. Everything was fine after I reinstall. My laptop runs cooler than it has been for streaming and recording. It was roughly 95 to 97 C, it is now around 65 to 70 C. I highly recommend this to everyone who loves Computer and looking to max everything out.
This model, SN850X, has built in dram compared to the SN770 which does not. This means that it handles I/O thrashing better and reduces the write wears from your page file and windows journaling and logging. It also uses less memory and cpu time compared to drives with no dram which must allocate additional system memory and cpu cycles in their operations. It will also perform noticeably better when close to being full compared to drives with no onboard dram.I have two of the 2TB SN850x's in my 2021 ROG Zephyrus G15 GA503QR. Load times are very good and always CPU bound and the power draw for two of the SN850X 2TB drives is lower than the one 1TB stock drive that came with my laptopWhen on sale the value is Five stars, when it is not I'd give it four stars.I ...

Absolutely based storage unit. This bonafide top tier piece of engineering is everything it claims to be short of the read speeds diminishing returns after + or - 50% capacity. Something still hampering the SSD revolution. I have heard whispers of storage maintenence technoques to subdue the diminishing returns of SSD's but I have yet to discover them myself. Nontheless there is no denying the read write speeds of these units, and make no misake, these are absolute UNITS if you known what i mean. If you dont, then i mean aay goodbye to prolonged boot up times and application loading as well long stretches of waiting to save documents As well as songs and video games. Ingenious engineering is the least i could say about these new drives. Capacity is limited as are ... MoreAbsolutely based storage unit.

If only we could figure out how to maintain read write speeds out of the box as we increase capacity.
Fast and works as advertised. I purchased this as an expanded storage for my PlayStation 5 Pro. The preinstalled heatsink is a necessity when used on a PS5. PlayStation 5 read speeds reported at 6,600Mbps. A little less than advertised by likely due to the PS5 hardware interface limitations than the drive itself.This SSD comes with dram so it’s ideal for use with PlayStation. Other lower cost SSDs might not have the dram and relies on HBM (memory from the host machine) for caching, this is fine for PC and possibly for PlayStations in most use cases. Just note that the PlayStation 5 does not support HBM.I have had good experiences with Western Digital drives and this one is no difference. The drives are reliable and is speedy as advertised.
So I bought this in preparation for the PS5 Pro. Have a 2TB WD SSD in my launch PS5. Moved over the contents of that drive to an external SSD. Removed it and put in the SN850X. The PS5 recognized it immediately. I am currently moving everything from the external SSD to it so when I get my pro all I have to do and remove it and put it in. Same exact specs as the Playstation branded model for $100 less. Plus got a $50 gift card for spending over $500. If I had to nit pick anything its that Best Buy shipped it in a non padded bag. Luckily it was fine but you'd think they would ship a $900 SSD in a box or at the very least a padded bag. ***Do better Best Buy!!!*** Also want to say this is my 2nd time purchasing anything at Best Buy in over 2 years. I bought an open box ... MoreSo I bought this in preparation for the PS5 Pro. Have a 2TB WD SSD in my launch PS5. Moved over the contents of that drive to an external SSD.

I bought an open box portal while visiting family up north a week earlier and then decided I probably would not use it so returned it at my local Best Buy in FL I had planned on getting the 4 TB drive but then decided to go for the 8TB. And I was in Best Buy every week before. I was really annoyed with how they handled the change to the Rewards program. Not that they changed it because I get things change. What annoyed me is that I was Elite Plus for many years and when they changed it they took away 7 months of Elite Plus status that I spent close to 6k the year before to get. So I decided I would take my money elsewhere. And I did for 2 years. But gotta be honest it felt good walking in there. The employees in my area are top notch and are always ready to help.
First off, I want to mention one thing. Best Buy, in a very "clever" way, lists this drive under a different model number than everyone else. It's the same exact product as say, Amazon sells, and bestbuy.com even links to the Product Sheet from this drive's page that show a different model number than BB lists it under. What does it mean? Well the drive is exactly the same, but if you do happen to find a cheaper price, as I did, BB will 100% refuse to match it because "it's a different model number". Very slick. And this is not the only item they do this trick with, so be careful when you shop, is all I can say.However, as tempted as I was to give this review a lower rating because of the issue described above, I can't penalize an excellent product like that.

I used to be all about Samsung SSDs, and they're still good, but I happened to have a picky computer, that seems to always act up with Samsung drives, even thought they do work fine in other devices, but WD work perfectly. So I switched to all SN850X drives in my system, and the 4TB was the latest addition. No issues at all. The temps are good with a motherboard heatsink, it's fast, of course, and it's a good deal, when compared with its closest competitor, the 990 Pro, I believe you're getting a better, more reliable drive from WD, at a slightly lower price. I recommend it 100%.
