I hadn't really looked into it much further. It was weird. I ran it twice consecutively. One time I got 1000 write and 2 minutes later I got 2200. Reads are consistently 3400. I dunno. I'll get to it at some point.

Yeah exact same behavior I'm running into. Seems to be better after a cold boot as well... Run CDM 3 times in a row, first 2x will show 3000write, then 1000-1500 randomly. It is my boot drive so not sure if something else is just hogging the disk...

If you are curious I did look into this more since it was bugging me. I finally saw this in a review. Once the pseudo-SLC cache gets used up it drops to the native TLC flash speed - same for any TLC drive:

"Because it has a Phison E12 NVMe controller at its heart, we know the Silicon Power P34A80 features an SLC write cache. After testing, we can see that it is capable of absorbing up to 24GB of data at 3GBps before performance degrades to native direct to TLC write speeds.
After the cache fills, write performance will degrade to just over 1GBps until it has a break to recover. Here it ties for fourth place overall."
