Hi guys,
I have a brand new Hackintosh, and a strange problem appears with my Samsung 970 EVO Plus 256GB.
Writing speed is dropping for no reason, and reading speed seems a little bit under his capabilities (see screenshot).
Do you have any idea what could cause this problem ?
I have the feeling its arriving especially with big files, in Disk Speed Test writing speed is around 2100 MB/s with 1GB files, but for larger files, speed is dropping.
Firmware is up to date for the SSD.
I have just added NVMeFix.kext to the boot but nothing has changed so far.
Thanks for your help !

Hello,
Just to let you know the resolution of my case :
- I have made a fresh install and disable Filevault, and the speed in writing/reading mode was a little bit better. But still, there were issues with writing, speed was dropping round 200/300 Mb/s.
- Nothing seemed to help so, I decided to change the disc, I have bought a WD Black SN750, and wooooo! No more issue, full speed in writing, almost full in reading mode (around 2900 Mb/s).
Using Filevault here, hasn't changed anything in the speed behavior, everything is fine with this new disc.
So, I strongly suggest to avoid using Samsung 970 EVO Pluslus in your Hackintosh, regarding my experience and a lots of things I have red on this forum, it is not the best idea.
Cheers.
