tiju1000 Posted October 18, 2020 Share Posted October 18, 2020 Hi, first post, I'm trying Unraid, disk are connected to a LSI 9300-8i controller on the PCI 16x port. CPU is a I7-8700k and motherboard is a Gigabyte z370-n. Yesterday I installed one of those 8TB Western Digital white label and started that preclean operation. This morning I'm at 14h, the step 1 ( pre-read) is at 88% done, Average speed 143 MB/s Nothing else is running on the server, I stopped the Plex and all other VM's. Average CPU load is around 10-15% during the operation. Is there anything I did wrong Thierry Quote Link to comment
trurl Posted October 18, 2020 Share Posted October 18, 2020 Seems normal to me. If you want us to look closer Go to Tools - Diagnostics and attach the complete Diagnostics ZIP file to your NEXT post in this thread. Quote Link to comment

Is there anything I did wrong Thierry That's normal, just running preclear on a shucked Prime Day 8TB WD drive, it took a little over 17 hours for the first read averaging 130MB/s. They slow down quite a lot on the inner tracks at the end. Keep in mind that parity checks etc will take the same time. Quote Link to comment
