I think the Samsung 980 posts numbers north of these figures, but only slightly.

For perspective folks, if I created a RAMDisk and ran CrystalMark, you would get throughput numbers similar to this SSD on your DDR4 2666Mhz/3200Mhz Dual Channel RAM. Now whether that's fully accurate, or representative of a system or software bottleneck limiting throughput is unclear, but food for thought. Theoretical thoroughputs should be higher, but this is what's reported in the synthetic benches.

The future of this technology includes but is not limited to:
- True Open World Gaming: XSX, PS5
- In-Memory Computing: In the pipeline, an eventual win.

Great price for one of the, if not the top Gen 4 SSD out there... Top three are this SSD, the Samsung 980 Pro and XPG Gammix S70 with the newest Innogrit controller, although you could still mix the Sabrent Rocket 4 Plus in there.

Good price indeed for a Gen4. But, and this is a genuine question, can you really tell the difference IRL between this and a Gen3? You've all seen the LTT video showing that they couldn't even differentiate between NVMe and SATA, which is almost unbelievable.

Would you rather get this, or a 1TB Gen3 for $153??

What the heck, I'm now tempted to get both -- this SN850 for my boot drive (great IOPS) and a pair of Crucial 1TB P5's in raid 0 for gaming/data.

The reason most people can't tell the difference between SATA and NVMe is that for typical day to day tasks, the extra speed is wasted anyways. If your car can hit 200+ km/h but you're driving in the city, you're barely gonna feel any extra power. So for most people, this would be a colossal waste of money. Less so if you actually do work that does heavy writes, but most people don't do that. Buy a small Gen 4 as a boot drive is probably a waste of money since you won't really be able to take advantage of the extra speed there anyways.

As for running two NVMe in raid 0, it's generally a bad idea. Again, the benefits don't end up being large, and while SSD are generally much more reliable than HDDs, when they do go, they tend to give less warning. For gaming and data, the differences would be non-existent. You'll notice it if transferring directly to/from a gen 4 drive but how often do you actually do that.

Thank you Op! Bought one right away. Now I am faced with a dilemma. Just picked up a Asus Tuf B550M Wifi due to the combo sale with the 3700x at Canada Computers. Also picked us the WD SN750 a few days ago. Now it sort of tempts me to get a X570 instead.

Still thinking if I should keep or return the SN750.

I think the SN750 and the SN850 maxes out on what B550 has to offer.

Got one. Thanks OP!

I'm looking forward to trying out in its "Gaming Mode".

Doesn't it remain to be seen whether PCi-E v4.0 drives will really be necessary for fast in-game loading, at least on PC? I would think that a good PCI-E v3.0 drive at over 3GB/s sequential reads will likely do a good job. I think even PCI-E v3.0 drives are still pretty rare - I would hope that Microsoft won't require v4.0 drives for this technology.

When it deploys on PCs, you'll like need a 4.0 drive to get maximum gaming benefit.

Already the PS5 requires it for the fast in-game open world navigation you saw trailers of in the Fall of 2020.

I got this disk and I was able to get around 6000mb/s seq read which is great.

Truly amazing. That is the same speed as DDR RAM and faster than RDRAM 2000-2002.

Yeah but that’s sequential read, ram are still a lot better for random 4K read
