This is a decent deal for a high end 4tb ssd considering the current state of the market. Ssd prices have been increasing from their low at the end of November, in large part due to the cutting of production by western memory producers and trade restrictions against Chinese memory producer ymtc.

The western digital black sn850x is a high end pcie gen 4 tlc ssd with dram, and is well suited for use as a boot drive and any applications where high performance is beneficial. If you're looking for a 4tb non-boot drive that'll primarily be used for static storage and/or games which don't support directstorage, then the sn850x is overkill. It sits firmly in the upper echelons of pcie gen 4 drives according to most reviews, and has no glaring flaws in performance, endurance, or reliability. Real world performance differences between high end gen 4 ssds (lower end drives, particularly without dram, may be slower to a meaningful degree) are essentially negligible, so you should primarily purchase a high end drive based off of reliability and price. The 2400tbw (600tbw per tb) endurance rating is fairly standard for a high end ssd, and should be vastly overkill for 99% of users. According to several post's I've seen, while the 4tb sn850x is technically a double sided drive, it is thinner than most double sided drives and therefore may potentially fit in m.2 slots designed for single sided drives. Its power efficiency and thermal performance is fairly good but not exceptional, it's an acceptable option for laptops and builds with poor airflow. A heatsink may be somewhat beneficial, but as long as it's in a build with decent airflow a heatsink should be unnecessary. Here's a review of the 2tb version of the sn850x (the 4tb version doesn't seem to have been professionally reviewed by any reputable sites): https://www.tomshardware.com/revi...in-black/3

The only meaningful downside to the sn850x is a lack of advertised hardware 256 bit aes encryption. This is meaningless if you don't plan on encrypting your ssd. However, if you would be using windows bitlocker with this drive, performance suffers with bitlocker software encryption. In recent months WD has updated the sn850x's datasheet to indicate it is tcg opal v2.01 compliant, and I've seen some claims on forums that hardware encryption is possible. It's possible in the future that firmware updates will enable hardware encryption for use with windows bitlocker, but at this moment it remains software encryption only. Here's tomshardware analyzing the effect of software bitlocker encryption on ssd performance: https://www.tomshardware.com/news...erformance

The WD dashboard application (necessary for updating the ssd firmware) is somewhat buggy but all around functional in my experience. It certainly isn't nearly as good as the samsung magician software, but you shouldn't need to use the dashboard much.

The sn850x comes with acronis true image for western digital, however that program has an extremely annoying quirk. Acronis true image comes with a "ransomware protection" driver built in, and that driver remains active even when you disable ransomware protection in acronis true image. This driver forcefully disables bypassio, a feature which reduces cpu overhead for reads and is a necessary part of directsorage. You can read about bypassio here: https://learn.microsoft.com/en-us...s/bypassio
While I believe you can use autoruns to disable the ransomware protection driver and still use acronis true image, I'd personally recommend just not bothering with it. Some other third party software, such as antivirus software, can disable bypoassio. The article I linked above has instructions for how to check bypassio status.

Overall, considering the current state of the market, this is a decent deal.

I can confirm this will fit in a PS5 despite being a double sided drive.

I put a 3rd part heatsink on it.

I also used an aftermarket plate for better airflow.

Everything is running great with no throttling.

This is a lukewarm deal and that also because manipulation of vVME, SSD prices. Realistically this should be sold at $160-ish.

Thought mac mini cannot be upgraded…
External TB4 enclosure. Can do 2500/2500. Not full speed but good enough.

Was thinking of purchasing a 4TB NVME SSD for my thunderbolt enclosure for Time Machine backups.
Anyone had experience with this drive for said purpose?
Goal is to maximize the speed of backups so I can plug in, wait for a few seconds for the backup and unplug often (like each day).
It's overkill for the purpose of backups, but yes, it will work. Likewise, it would work great as a boot drive if ever necessary... MacOS tends to play better with WD controllers than the last few Samsung versions based on source1 [macrumors.com] for 3rd party upgrades and also based on feedback from people building hackintoshes. But if you aren't running your OS from it, this is irrelevant.

Great ssd. I got this around 6 months ago for the same price and it's been solid (pun intended). Only thing is that I never see 7000+ MB/s on my PS5 as advertised.
Yep, this is actually a slightly worse deal compared to the sale during Prime Day in July, even though the sticker price is the same. With No Rush Shipping in July, they offered 7% CB using the Amazon CC... Tops out at 6% CB right now. Not a huge difference, but interesting nonetheless.

I suppose we should be "thankful" we're still getting these deals at all, if the "buy now before the prices go up" blogs are to be believed.

going to raid 0 in my z790 14900k build.

should go well if i decide to play games locally,

my 10GB intel nic gives me close to 700-900MB/s to load games from my 300TB true nas scale server.

+1 Thank you OP. I've been looking for a 4TB. Now I have to figure out how to clone my boot drive and make this my primary.

Do you guys see the 2TB version of this dropping back to $89.99 again as it did this past summer?

Not likely.. BF prices didn't even hit the low from the Prime Day in October. NVME prices are creeping up. Will likely drop again at some point when a new model comes out and they start pushing these to clear shelves, but otherwise, unlikely to hit $90 again considering it didn't for BF.

Download a utility version of Acronis True Image from WD which works when you have a WD brand drive connected. It should be on their website.
