I don't believe Samsung's tools, either. I was buying 850 Pros for a while that my back of napkin math suggested were getting around .7 DWPD and still showed something like 83% cell life after two years. That also seemed too high to to be trusted.
The WD utility is useless, so I used the Samsung Magician. The results are the same (~41TB) but the Samsung only shows that amount, not as a percentage. I do have a 2TB 850 Pro (2048GB) that cost about $900 over 8 years ago. It has 22x life cycles at 98%, but has not been used in many years. It's probably the most expensive drive of any type I ever purchased other than that disastrous Intel U.2 SSD.

I have a box of 12 of those drives sitting right next to my trackball here. I don't understand why you've never bothered to RMA that drive. It has a five year warranty. I'm sure it could still be replaced.
I'm not saying there is anything wrong with the model of drive, just that mine died out quickly. It is quite possile that it was because I was using an M.2 adapter, although I found someone had used that Intel SSD with it and I used it for a couple of weeks. Obviously Intel sold many thousands of the U.2 drives for enterprise use.
I don't recall exacrtly why I did not submit the SSD for an RMA, other than that it contained data. It may not have had an OEM warranty and been past 30 days or maybe I was traveling.
I'm not sure why the Forum prohibits my functions.

There have been a few M.2 8TB TLC such as Sabrent, and now the Corsair is also making one. Despite that the smaller SSDs are less per GB, why are there not more 8TB M.2 SSds? The RocketPus has been going up in price over the past few months.

At a guess, there are more QLC NAND m.2 OEMs are probably looking at their offerings as most appealing to consumers, just as HDD vendors mostly market and sell SMR drives at the consumer level.

Storage is cool
I agree. Perhaps 8 TB is pushing the limits of current technology? I imagine it's easier to manage cooling, reliability and so on in the 3.5/2.5/EDSFF formats.
In the server space M.2 are more common as boot drives where I suppose they see a lot less activity than their carrier mounted friends who are fighting with database loads and whatnot 24/7.

My reasoning for getting proper tri-mode HBAs is that commonplace 2.5" SATA/SAS SSDs definitely top out at 4TB. I can still get 1DWD drives, which I see as a goal of any server drive life cycle. I don't particularly care about the PCIe data transfer rate (is it over 500MB/sec? Then it's fast enough) but I do care about capacity and life cycle. M.2 seems to cater to consumer limitations as well, which means QLC NAND and relatively low capacities. It's cheaper to get an HBA and an 8TB u.2 drive than one of those TLC m.2 guys and as a bonus, it can bring along 7 (or 15) more friends.
I'm not sure about the DWPD vs. the TBW. For marketing the DWPD makes sense, but is an SSD with twice the capacity and half the DWPD (same TBW) really any worse for example? I see DWPD specified at 128KB sequential and also 4K random. Maybe your server application can use a larger indirection unit to improve the DWPD. For example the 65000 IONS has only 0.3 DWPD at 4K randoms yet 1DWPD at 128K sequential. 0.3 DWPD may seem low, but that is 9TB/day on a 30.72TB drive. How many TB/day are you processing on that system?
The prickes seem to be out of control. It's now https://www.cdw.com/product/micron-6500-ion-ssd-enterprise-30.72-tb-u.3-pcie-4.0-x4-nvme-ta/7467127 $4100. The slighter older model 6500 Ionic was only ~$3200. I'm not sure the different part numbers are relevant to the high costs.

SSD prices fell to historical lows last year. I'm REALLY happy I have a stack of Intel 8TB u.2 drives right now because the supply for those evaporated in late February and I know I can't afford the current generation models.
So about a 25-33% hike for SSDs in general is normal? I recently read that somehow we all need AI computers, and industry must run AI also. I wonder if it is really transformational or partly a scam to sell more SSDS, RAM, video cards, etc.?

DRAM prices can fluctuate in a similar fashion to other memory types. No manufacturer wants their goods at their lowest prices and you must remember other times that we've seen peaks and troughs in that pricing.

I saw prices of commodity SSDs drop to as low as $35/TB last year. Now it seems $45 to $50 is about the best deal you can get. Longer term of course, the trend is still down, as it's been with DRAM.

I'm guess that's low-end commodity stuff which people on a budget buy. I definitely did see SSDs going for $35/TB last year. I also recall 8TB HDDs going for $100, give or take. If fact, here we go:
$13.75/TB
I'm looking forward to the $5/TB SSDs the chart predicts by 2030.

The 1TB NVME drive I had my eye on at the start of the year spiked from 55 dollars up to 70 recently. Guess I'm waiting a bit longer, even if this laptop desperately cries out for more than 512GB -- games are very rough on storage these days, and I've got a few big-ticket items installed.
