Intel RST Raid 5 with 6 HDDs incredible slow

Question

maybe someone can help.

Since I upgrade our Raid5 from 4 to 6 HDDs the write-performance is VERY poor. Read is more than 700 MB/s but write is less than 30 MB/s Cache-Modus is Write-Back

System specifications: Asrock H370M-ITX/ac 32 GB RAM DDR4 WD Blue SN500 6 x WD60EFRX (WD RED 6TB) Windows Server 2019 Intel RST 17.7.0.1006

What was the write performance previously? – Havegooda Nov 08 '19 at 19:47 — Havegooda, Nov 08 '19 at 19:47
don't know exactly, but much more than 250 MB/s – dj wurst Nov 10 '19 at 16:56 — dj wurst, Nov 10 '19 at 16:56
