I have a full size 4U server NAS. I almost got these drives during their last sale, due to the newer technology and huge power efficiency (less heat, on 24/7)

Th only reason I didn't is because I opted for 2x 8TB.
If this drive came in 8TB, I would have purchased it as my first pick.

But, every usage is different. for my personal media use case, this NVME was more than capable.

The Sandisk direct is still going on for this same model. It fluctuates though. And you have to buy two. Right now Before taxes it's 390.08 for a pair. It was 403 and $423 at other times.


But i only need one right now as i jumped on the B&H Samsung ones going for $200.

It should be better. But in the end there's not going to be that much difference. From what people are running into with these Ultra Low cost multi m.2 slot devices people are turning into NAS's are that you want them to be low powered because the power supplies they strap them with are pretty small.

It does have HMB though so performance will be very similar for 90% of use cases.

So from what I could find, the main difference between the two is that the sn850x has Dram, while the sn7100 does not. From what I could find in western digital's own documentation, it seems that the sn7100 is designed to be a high performance drive like the 850x, but better optimized to be more energy efficient for laptops and handhelds. So, based on this info, unless power efficiency is a priority for you, I would go for the sn850x.

Argh. I JUST ordered a Team Group G50 4TB for my NVR (UCG-Fiber), then this pops up. Do I want to return the Team Group and get this? Is returning/re-ordering really worth the increased power efficiency?
