Hello Samsung Community Users,
At Samsung we value customer feedback and we are always working on improving ourselves and our customer’s experiences.
We apologize for any inconvenience caused by the symptoms of the 980 Pro not recovering write performance, this is due to the turbo write area being exhausted.
Samsung is preparing a new version of the 980 Pro firmware so that it can be updated at the end of April to resolve the problem.
We appreciate your patience while we work on resolving the issue.
What about linux?I get normal read and write speeds at windows 10 and 7gb read speed at linux but write speed is at 500/mbs. Got two of them and i am really disappointed cause linux gives a 15-25% performance gain on the cpu intensive tasks i do.I also tried latest kernel and of course firmware is the latest. I also checked my fathers older 970 evo and it was also capped at ~550 mb/s. Would be nice to have that issue resolved. There are some onilne benchmarks that show the problem and they also show competitor drives achieving advertised speeds. cpuy is 5950x and mainboard asus x570 gaming-e. Any official response of acknowledging the issue and taking care of it for linux users would be nice
I can confirm that drive's write speed is indeed falling down after some time to around 2500 MB/s and it doesn't go up afterwards. I have had full speed for some time, since I pulled out the drive and reinstalled it in the NVMe slot. Then I had to change something in the BIOS, and the infamous Gigabyte self reset occurred, after which the write speed fell down. I tried the benchmark couple of times after that, and it was not going up, as you can see from the screenshot. It is obvious that the drive can go at the full speed, but there is a bug in the firmware that is preventing it at some point, probably related to the mentioned cache.
@userYwowh3mtHW If the issue is back with you, please unmark my previous post as solution, because clearly it is only a temporal solution to reset the cache.
