Hello Framework community,
I have just bought a 1tb storage card from Framework, and it was surprisingly disappointing.
My main frustration is its write speeds falling to 20-30mb/s on what seems to be the exhaustion of SLC cache. Whenever my file transfer fills more than 1/3 of the remaining storage, the speed won’t get any higher. After a pause, though, it accelerates until 1/3 of the free space is filled again.
I know it is expected behavior but 20mb/s seems too low.
Can anybody confirm whether this is the speed we are supposed to get on continuous writes?

In addition, it turned out to be not as friendly plug-and-play experience as I expected it to be:
-
The card sporadically disconnects on writing when plugged into the front (usb3) ports of my 7460u framework, although it is very stable when connected to the rear (usb4) ports.
-
Also, the default exFAT filesystem seems to be the culprit of my initial performance problems: I had to reformat it to NTFS and enable performance mode in Windows device settings to reach the advertised 800mb/s speeds (which fall nevertheless).
-
Finally, it gets concerningly hot, as reported previously, when mounted but not in use. I disassembled it, and located the thermal pad was installed correctly. Yet, the speed degradation doesn’t seem to correlate with the observed temperature in my case.
Can anybody confirm these tradeoffs and nuances are inherent to this product?
Or is this my unit has a faulty controller or something

The card in question is FRACCFBZ0A.
My setup is 7460u Framework 13 + WIndows 11, which has been working perfectly fine with many other storage devices.
I am a happy user of the 250gb storage card, but I am in no position to compare them because I use it for Linux, not for large file transfers. It is stable and performant enough, though.
I also tried to test the card on Debian but write performance was even worse there. I assume it was due to (de/en)cryption and filesystem overheads.
