Random performance issue

[lucas0x7E]

Hello everyone!

I built a new TrueNAS CORE 13 system and am currently moving large amounts of data to it.

Unfortunately the performance is extremely fluctuating, sometimes I get 300 MiB/s, then it goes down to some bytes / second. Please see the screenshots below.

Both writing and reading Windows SMB clients repeatedly get the error messages Error 0x8007003B: An unexpected network error has occurred. and Error 0x80070079: The semaphore timeout period has expired.. Furthermore the web interface subjectively seems to be lagging.

Could you provide some hints for starting troubleshooting?

Dear All!
Please forget this thread; it seems, the Seagate Enterprise Capacity 6 GB ST6000NM0024-1HT are failing. They are from 2016.
I will buy new disks and report the results.
Thank you!
