Hello,
I'm currently in the process of replacing each of my six disks I have in my QNAP. I'm moving away from my Segate Exos 10 TB drives and moving towards 20 tb segate iron wolf pro drives.

During this process, I haven't had too many issues except for a progressively worsening rebuild speed as I near completion. In the beginning, I was achieving 250 MBps and the rebuild took approximately 13 hours (not a big deal). However, as soon as I hit the half way mark I started to experience an inconsistent 150 MBps to 200 MBps. My question has become two fold:
1)Why did the performance begin to degrade?
2)Is there any possible way to increase the speed?
Side note, I've modified the TVS-672x to run on an i7-9700k and I'm running 32 gb of RAM DDR4 2666 MHz with a closed water loop on the CPU to account for the 95 TDP so I'm certain I can push it harder. https://www.amazon.com/gp/product/B08C4 ... UTF8&psc=1.

200MB/S rebuild speed sounds about as fast as you can get (sequential write speed maximum of the rebuilding disk)
