Micron 2600 QLC SSD uses flexible caching to offer TLC-like performance—7,200 MB/s reads and 6,500 MB/s writes push the limits of PCIe 4.0 : Read more

Flexible caching sounds like something that will make a brand new drive look better in a short term review, while not really being beneficial to a real user using a typically-loaded drive.

I'd call that cheating, or at least misleading

Oomph, those endurance numbers...

And crappy capacities to further put this in the instant fail basket. Tell me again why we introduced QLC rubbish when it can't even offer higher capacity than TLC after all this time. With 8TB TLC drives widely available, I was expecting 16TB QLC drives by now.

In a typical desktop enviroment you won't be running out of those even after it's considered lifespan.

Theoretically they shouldn't, but there are people that like to fill their drives to >90% of capacity, something you shouldn't do with SSDs.
Having <16GB RAM has the effect of more page file usage, further increasing wear rate, and is surprisingly too common in cheapo laptops.

I'm using primocache in combination, with a UPS.

Primocache offers the option to stall the writing to pagefile and saves it in RAM before it does that every, lets say 300 seconds. Advantage is a must healthier SSD, quite snappy OS and less wear long run.

UPS is needed because if power does cut out, your in a world of trouble if the writeback did not succeed.

Adaptive Write Technology starts by writing new data in SLC mode. Once SLC is full, it switches to TLC mode. After both SLC and TLC are filled, the technology moves the data to QLC mode when the SSD is idle. Finally, it frees up the SLC and TLC regions to store new data. By switching between NAND modes, Adaptive Write Technology ensures the drive offers the fastest possible write performance.

I'm pretty sure we've seen behavior like that, in the "sustained write" benchmarks, in SSD reviews. There are definitely drives which have more than 2 tiers of write speeds.

I'd agree, except that I think most people tend to run their SSDs close to max capacity, for at least a significant amount of their lifespan. The size of the caches is proportional to how much free space you have, in which case it's worth having that TLC tier because the SLC cache of a nearly-full drive would be small enough that it wouldn't be hard to fill it.

I dunno. I had a couple situations where Firefox was generating several TB of host writes per day. I noticed my disk LED continually flashing and checked to see what was causing it. I think it was one or more web pages, continually writing lots of cookies.

Yeah, but it depends on how sophisticated the wear-leveling is. Ideally, the SSD should be periodically refreshing its blocks and migrating data to even out wear, in the process.
