SSD reading data non-stop after sleep

Since replacing my fusion drive for a SSD on my late 2017 iMac, I've had an issue where after sleep the disk reads around 60mb/s nonstop. Only read, no write. And it never stops. When this happens MacOs is quite slow and I'm worried that the SSD might wear off. Hundreds of gigs of data end up being read for no reason.


I've tried reinstalling mac os completely, wiped out everything and installed the most recent mac os version. This has not solved the problem. I've had this problem since at least 3 macos versions.


When I reboot macos, things are fine. Only when I let the computer idle for some time does this happen, and once this happens it never stops unless I reboot. I tried disabling any kind of sleep but it still occurs.


I've searched the web everywhere, haven't found any solution. Any help would be greatly appreciated. Thanks!
