Probably the Solidigm (D7-P5520) or Micron (7500 Pro). I don't know whats with WD & Seagate.
Sadly Kioxia and Samsung are not on this list...
If you take the 12,8tb versions you get easy 2-3x the write endurance and 1,5-2x write IOPS, if you need that, or a simple overprovisioning (~20-28%) via smaller namespace config will do it too in most cases.

I have one of these a d it just works and runs cool. FW is overrated if the device works well. I went through two micron drives before it that both lasted less than a week.
Probably would if I didn't just want the 16tb version. The one I grabbed is the CD8 and it idles at 40C without direct cooling needed.
Where they from the Micron 7400'er Series?
And i don't think Firmware is overrated when i see whats in the changelogs from the Samsung eSSD's... The pm9a3 is now matured enough and the firmware is unofficially obtainable.
The Kioxia FL6 Series look interesting, and the overall hardware-design from Kioxia looks really clean (and the cooling design), but no chance without FW updates.
OT: The P5800X works quite well, but limited capacity and a sad end (R.I.P. 3DXpoint).
I never saw an sm963 u.2 (MZQKW1T9HMJP), 12,6PB TBW... and an sm983 was never produced.
IIRC yeah, one lasted almost a week and the other less than 4 hours. Didn't get a chance to do much of a post mortem due to return windows but they both lost their partitions tables and couldn't be restored. I upgraded the firmware on the second one since I had time on my hands while waiting on the replacement from a different seller to do some research and hoped it would prevent the issue.
Kioxia are upgradable but, I can't find an image and think they might push one out through Linux fwupg possibly. But, I'm not tempting fate as it's working great as is.
there i saw it: Ahrefs SSD failure statistics and it's the Micron 7450 mentioned here, on the other hand the 9300 did it well.
It can/will hit every manufacturer at some point, i remember the IBM "Deathstar" a long time ago...
I still hope that i find the hxm7a04q firmware for the samsung sm883 and gxm1103q for sm863a someday
Went back and looked at the invoices and that's what I tried first. I have a rule though if it fails 2 times then it's not getting a 3rd attempt. I even swapped the carrier card with the 2nd attempt. I finally switched to a M2+cable instead of card for the 3rd / Kioxia just to rule out the PCB/slot being an issue.
Now, on the other hand someone I was talking to on another forum ordered a couple of 7450's and the only issue he had with them is having to mount fans to the HS on each one to keep them moderately cool. I didn't get a chance to really probe the Micron's or think to look at the temps closely since all of my gear generally runs cool anyway. Maybe there was a temp spike but, the error cropped up as an I/O error and upon reboot the drive just disappeared but was still showing up in command outputs just not able to execute fdisk on it or anything else. It reminded me of failing HDD/USB drives in the past. At least with those failures they were logically seen and recoverable data wise.
For whatever it's worth, I have a Micron 7400 Pro in E1.S form factor, I had to remove one side of the housing to fit it to my adapter, and when I did I found that all the blobs of thermally conductive silicone on the controller side were misplaced - the controller itself barely contacted the thermal goop just along one edge and most of the other chips on that side of the SSD had maybe 20% of their surface covered. If they had similar issues with the U.2/3 drives I could see some issues cropping up.
It also doesn't accept any of the firmware available from Micron, so not every one of their drives gets that support.

@nexox now that's interesting. I popped open one of my older SSDs and found it to not have any goop and looked like a couple of M2's sitting inside the casing but just on a single board. I didn't want to mess with the micron's though if it gave them a reason not to issue a refund at $1k/ea. I figured the finned exterior would be good for dissipation but obviously not the case. The Kioxia is more like a traditional 2.5" drive and probably would fit into a laptop if it had the right connector.
