Using four Western Digital HC550 18TB drives, I set up a RAIDZ array, but the read speed is slow. Drive model: HC550 18TB - WUH721818ALE6L4. On my TrueNAS Core server, I created a RAIDZ with these four HC550 drives, and the read speed is only 161 MB/s. However, when I switched to four Seagate drives, the RAIDZ read speed reached 500 MB/s. I have already troubleshooted the system and hardware (including the client). The HC550 drives can achieve a read speed of 450 MB/s in the shell using fio
, but the read speed drops to 161 MB/s when accessed from the connected client. What special configurations should I apply for the HC550 drives?
